Thank you for the detailed info and the tips, it’s much appreciated! With that to lead me in the right direction I was also able to find a possible solution for the home button without a workaround using an updated app, though it seems ymmv depending on whether or not Amazon can automatically reset it somehow. I have pretty much everything blocked so the home screen is usually empty except for my top row apps, so the button fix may work for me, but those workarounds may still be needed. Thanks again!
