The problem

I have configured Nova Launcher as my default. Since today or yesterday, I sometimes get greeted with BlissLauncher after unlocking.

After checking, the standard app for start is set to Bliss.

Setting it back to Nova works, but not on the long run, as it sometimes resets itself to Bliss again.

Steps to reproduce

Technical details

None at the moment.
