Samsung S21 Bluetooth problem

[Dirty Ming]

Not sure if this is the right section to ask?
My S21 connects to my van and car stereo as normal, but when I try and play music/podcasts from Spotify it shows the track playing but there's no sound.
I've deleted and re-paired the phone with both vehicles and still nothing. I can, however, connect it to my Sonos speaker at home and play music so the phone is still capable of communicating.

Try deleting your bluetooth data and cashe by going to settings, apps,

Then select the filter opposite "your apps"



Next select show system apps and "ok"



Then select the Bluetooth app, go to storage and then clear the data and cashe. After that restart your phone.

I can do all of that, until I get to the last part, when both "clear data" and "clear cache" are greyed out and nothing happens when they're pressed. It was working OK until a week ago

Got it sorted, at least for now. Rebooted the phone and it connected instantly.
