On upgrading my Sony Xperia 10 Plus Dual SIM mobile from the last early release build 18.104.22.168 to 22.214.171.124 I am now unable to start the BTtons app when selecting start and when returning to the home screen the app is just continuously spinning with Mpris proxy isn’t running. In turn I am no longer getting music information on the ford car stereo again.
I had similar issues previously on version 3.4… when upgrading from one version of 3.4 to the latest version of 126.96.36.199.
So a similar pattern. And then I found the only way to resolve it was to go back to Android 9 > Sailfish OS latest version which as you can imagine is a lengthy process each time there is an upgrade.
I did try uninstalling BTtons, removing the bluetooth car stereo from the mobile and re-pairing but that didn’t work.
Any other options would be very welcome or if anyone is having similar issues. If there is an easier solution I would love to hear.
