after update my BD Remote Control (Sony PS3 remote control) was not working.
the bluetooth connection page shows connected yes, but not working (press any button at controller nothing happens). it was neccessary to plug a wired mouse.
after delete and pair (trust and connect) it works after reboot (not immediately like default). but with the next reboot same issue again.
my workaround was downgrade to previous 12.0.1 via /storage/.update and wget as described in the wiki.
with 12.0.1 no issues with the remote controller. i repeat the update again for twice to 12.0.2, exact the same problem.
using bluetoothctl at 12.0.2 the reported issue is same. i remove the device with untrust and delete and pair again with trust and connect commands.
full reset with 12.0.2 was not solved the issue, with backup and restore settings.
