Amazon Fire Tablet Unpinning Randomly

Wondering if anyone else has the same issue as me.

I’ve got an Amazon Fire 8 wall-mounted tablet I’m running the HA app on. For probably the last year, it’s been completely fine, but in the previous few weeks, the app keeps randomly unpinning and going back to the home screen.

At first, I thought it was the toddler, but I’ve kept it out of reach, and it’s still doing it. I was unable to find anything on Amazon forums or here already. Does anyone have any ideas?
