Hi Pablo @lumaticsoft ,
Thank You for explanation. So as the cause is in fact Play Store policy, not the “Android 10 nor BT Stack” - First- I would like to re-check with You if “call starting” - (with no voice transmission over BT) still falls within the google restrictions, and I understand that this is part-time activity in the free time which is precious, and as months passed since initial request over the email- I would like to check with You if in case google policy blocks call starting - You see it possible to develop (add call starting possibility)(which is NOT full BT calling as explained) from the watch to the version 15, as “call reception” can be solved by Google phone app installation as shown earlier in this thread) and distribute this version outside of the play store - as paid version - as mentioned I declare 100$ for this development work. If there are a few others, which can donate to You - maybe this can initiate the work? What I can promise form my side is to prepare YT video that it works again (previous one here https://www.youtube.com/watch?v=fdvKLo_uAhs&t=1597s )
Regards,
Luk
