The lock screen again ...
I use an Xcover 4s with android 10 and locus 3.46.2, "Screen timeout" is 1 min.
In locus Ssettings | Controlling | Display | Disable screen lock: All screen locks on!
Recording a track, locking and unlocking with hardware button works - locus stays in front.
After "screen timeout" unlocking with hardware button flashes locus but then shows the lock screen!
