Did this ever get resolved. I have exactly the same issue with an android phone. Worked perfectly on 3 year old GS, new bike last summer and it worked fine, bike been garaged for 6 months due to health issues which are now sorted, but the connected app won’t work. Deleted and reinstalled half a dozen times, phone restarted half a dozen times, starts to record but stops quickly.
The datatrack app is working fine.
One caveat, it’s a works phone and there are some data restrictions that I don’t have any control of, but that would stop the datatrack working…..wouldn’t it?
Thanks in advance
