More than likely is, I still cannot get used to the hill start control, want to trust it but, old habits come back.
GSAP Upshift Issues - anyone else?

I had the same issue. Turns out it was operator error. Using GSAP you have to be on or off the gas dependent on direction of shift. Anything else results in ‘Buckaroo’ type moments and the occasional moment of silence when the engine is killed but there’s no shifting being done.

Erm... that's not exactly true.
I rode another GSA (demo bike) and I didn't have to care too much about rev, speed or km. It just shifts up and down so smoothly.
Get yours checked out.
Mine is in BMW now... awaiting update, reset and possibly they change the GSAP unit for a new one.
My bike is 2018, 3000km new.

Interesting - that sounds exactly my mine. The gearshift is so hard to move in GSAP that I rarely use it at all, whereas with the clucth it's beautifully light and accurate. Barely get any sort of blip on down changes either - just feels like I'm crashing it down the gears. It's basically shit whereas my much old S1000RR is super smooth and light (up only)
Mine's been difficult to upshift from day 1. OKish downshift.
Just had it serviced and the upshifts are a little better but the lever is still more difficult to operate than with the clutch.
I end up doing clutchless upshifts but not using the GSAP , by just dipping the throttle. Much better,

Mhhhh, with the GSAP installed, I don't think it's possible to achieve a clutchless upshift without triggering the system.... ???
I'm tuned. Any update??
It is if you drop the revs. It goes into gear just nice, if I keep the revs up the lever is harder to shift. It needs more force.

Frustrating gearshift
I`ve had my GS two weeks and have done 1500 miles. I`m still struggling with GSAP. Never smooth 1-2 and 2-3, so always use the clutch for a smooth change. 3-4-5-6 good between 4 - 5K rpm but jerky otherwise. I have taken to easing the throttle on upshifts for smoother changes. Downshifts are much better with a firmer than normal pressure on the lever. It does occasionly forget to "blip" the throttle when going into first making me look like a complete amatuer
The bikes new to me, so will keep trying.

On my S1000XR it was faultless up and down the box. On my 2018 GS, up - 1-2-3 clutch, 4,5,6 GSAP faultless but on an open throttle.
Downshift, all gears faultless but on a closed throttle.

But what convinces you GSAP didn't trigger? I know how a clutchless upshift works on a regular bike, I just don't think rev matching is all it takes to inhibit the system. From what I understood, if a gear change is requested in the absence of clutch lever pressure, the GSAP will try to works it's magic, essentially cutting the throttle(or blipping it for downshifts) in order to rev match and execute what is essentially an automated clutchless gear shift.
Maybe, you dropping the revs helps for smoother GSAP upshifts but in my experience it's not the case at all! If I decelerate prior or during an upshift it's even more jerky and awkward, and that is IF the shift occurs at all... I wouldn't rule out a defective GSAP unit in your case.
On the other hand, the fact that GSAP shifts need more strength and a more deliberate movement is by design and not a fault with your unit. GSAP does not care one bit for sloppiness, but I agree there is a big difference in GSAP response across bikes, even from the same gen and similar mileage, and that's a bit disconcerting. GSAP is a skill that needs to be honed but that doesn't transfer to other bikes as each one seem to set in differently.

I have done a comparison with a demo bike with less km than mine (3000km) and the demo bike shifts almost effortlessly in COLD engine conditions.It is not the rider. It is the GSAP or the settings. Will this be correctable? I don't know. My bike is ready for collection but the rain today has a weather warning...so I will wait til I retrieve my GSA.

Some mornings, when I take my bike from cold, I feel like the GSAP is smoother. Difficult to quantify that kind of gut feeling and it may be the whole gearbox/engine feeling less "sawing machine" like, still, there is a noticeable difference. Oil quality/properties in the gearbox?

1. HOLD the revs constant when shifting
2. Rev up and hold and kick to shift UP
3. Close throttle fully to kick to shift DOWN
....when I was riding the demo bike, I did not have to "focus" on these guidelines...the shifter just GLIDES smoothly into the next gear (UP/DOWN) with a slight tap of the toe/foot.
"What? Is that even possible? "
Those were my exact thoughts when I rode the DEMO...my heart sank because my own GSA shifts hard and I can in fact injure my toe or break the lever eventually.
Mainly because I've read lots of times that even a slight reduction in throttle cancels the GSAP.
I have to agree with the observation regarding the feel of the GSAP in that somedays it just seems to work and others it doesnt.

I may be wrong but I think your GSAP just work and you happen to have learned a technique that make it smoother on your bike.
On my bikes(2018 GS and 2015 RS), cancelled GSAP attempts prevents me to shift gear altogether. No or too few throttle on upshifts, or too much when downshifting result in the action on the gear lever being totally ignored, it doesn't revert to just work as if it wasn't there. Botched GSAP shifts in the other hand result in more jerk, the bike lurching forward, or the rear tire micro-skidding, or the gear going to a false neutral, or the gearbox starting to emit very unpleasant grinding noises, or no blipping of the throttle... that's what I get sometimes when I half ass it.
My point is, if your bike is equipped with a working GSAP, only way to inhibit it is to use the clutch, any other attempts result in a GSAP shift, cancelled, botched or smooth.
