Have tried twice to get action on this via Minecraft support and failed.
Have now gone to Amazon to point out the app doesn't work on 7th Gen Fire 10. Hopefully Mojang will look at the issue.
The Android Xbox app, that records login activity, says that Minecraft did run for the login at the time the app bombed out.
I installed mine through Play Store not AppStore. Play is still on 1.17.32 and so it still doesn't work. I'll have to pay again to install from AppStore. Is this just a delay or is 1.17.33 not getting released on Play Store?
