Agree with you ChristineKing3.....amazing this critical use case of having full permissions in Word/Excel on Android devices to remove personal docs from the Word/Excel App remains unfixed for all these years.
I have tried uninstalling the Android Word/Excel apps and reinstalling and it did no good. I have spent over 2 hours with Google tech support to resolve the Word/Excel permission issues and even they couldn't fix it. They got so frustrated that they sent me a replacement Google Pixel phone! (still didn't fix the problem).
Amazing Microsoft and Google haven fixed this Android/MSFT Permissions issue yet.
I find myself using Google docs and sheets more and more...guess that's what Google wants us Android phone users to do:)
Hope someone from Microsoft actually reads this message board and could chime in with a response from Microsoft on this bug fix with Android phones.
Thanks
