That's a completely different problem. The stable release has not been updated for a good while. I've not had that issue pop up on both my OP7TP and S5e. What phone do you have?
Ah just me clutching at straws then. S10 here.
It's weird, Nova is the default but it's almost like stock realises it's not top dog and takes over the screen. Seemed to do it without even swiping home/back etc while in an app which was more annoying. The other thing that happened was I couldn't access recent apps. I think I did read something about Google 'fixing' something the current version of Android which was out of the Nova devs control.
