Back button not working on Fire TV Cube only in Prime

Is anyone having this problem using their remote on Prime?

I have a Fire TC Cube using with an x1.
A couple of days ago (7/23/26), I was watching a show on Prime. When the show was over I couldn’t exit the show and back out of it. I then noticed that I couldn’t exit out of Prime using the back button. On all of my other apps, back button worked. The Fire TV remote worked and I could back out of a Prime show and back out of the Prime app.

I have tried everything I can think of.

- I reset my Hub and redid the entire programming and it still didn’t work.
- swapped the X1 remote out
- reset the Fire TV cube

I installed a different cube and it worked perfectly and it stopped working a few hours later.

After hours of trial and error I found the problem. The newest release of Prime PVFV-321.0078-L , the back button doesn’t work in Prime

I did a system reset and restored from a week old backup. It installed Prime, release PVTV-121.0077-L. So far it is working correctly.

I have disabled the auto update for Prime.

Anyone?
