Authentication Required–To view the Items in this Folder, you need to authenticate...
In the Files app, I have set up my Google Drive app and my iAnnotate app as locations that Files can access for document use/editing/etc. Now when I try to access the files in these locations, I receive that says, “Authentication Required. To view the items in this folder, you need to authenticate in the Google Drive app.” There is a link to open the Google Drive app. Selecting the link opens the app, which has already been authenticated. When I switch back to the Files app, the same thing happens again. This also happens in the iAnnotate app, which is not even a secure app. It does not have an authentication mechanism.
What’s the problem here? Screen shots of the “authentication required” messages are attached.
