I'm not good with git, so I just deleted the whole local repository and
cloned it again.  So I know it is working correctly now on v32.0-60. Same
for Android mythfrontend. Moving Android mythfrontend to the latest fixed a
lot of problems for the FireTV 4K Max. It never worked like the regular
FireTV 4K for me until now.

If you know who creates and posts the Android version officially, please
let them know it's now time to rebuild and post.
