Onedrive Content Unavailable in iPad Files app

First, Apple isn't here as this is a user to user only forum. Second, if you read the very thread you responded to, a few posts above someone seems to have found the solution, so read the thread to see what they figured out.

I have this problems on brand-new iPad Mini 5s and iPad Pro with iOS 14. From what I've read online, this was happening with iOS 13. This work-around does not work, because the ... icon is greyed out, so I cannot change the sort-order... https://www.youtube.com/watch?v=5CPomVQ28yI&feature=youtu.be Works with the individual apps for OneDrive and Google Drive, but not through Files. Makes it difficult for my kids to move files around.

I saw something similar with the BrightSpace Portfolio app, too, but this one showed a little more, saying that the app could not authenticate to Google Drive. It all works correctly in iOS 12 on an iPad Mini 3.

Since this is so widespread, I cannot believe it's just the developers who are at fault. The only thing that may be common (for my devices): the iPad Minis are managed through Screen Time (although I've removed this and tried), and my iPad Pro is managed via InTune. This leads me to wonder if it's some authentication mechanism that iOS 13/14 implement.

I found one solution.

Go to Files app.

On Top in left section click in 3 dots and select Edit sidebar.

Now slide buttons to onedrive to ON.

You should now sww Onedrive in Files app..

Hope this solves..

A final step if you can't get it working correctly is to restore your iPad from backup. See this link for guidance --> Restore your iPhone, iPad, or iPod touch from a backup - Apple Support

Issue with IPad Attaching files from One Drive. I get this message. Please help!

There could simply be an issue with the server you connect to for OneDrive. If you open OneDrive from the OneDrive app, can you access the folder and files directly in the app?

I don't really know what else I can suggest. OneDrive works well from inside the Files app or OneDrive app on my iPad Pro 11 2018.

Negative on that one.

I tried it, no luck.

Sorry. Either reach out to Apple since it's not working in the Files App or Microsoft since it's their interface to the files App.

Your issue may be completely different since by your own admission you are using Beta software. Beta software cannot be discussed on this forum however.

Ciao.
