Links to uploaded files getting error

Starting today all links to uploaded files are getting the following error:

404 - File or directory not found.

We are not able to access any of the uploaded files through the app. These files are stored in Google Drive. We can access the files directly in Google Drive, but not through the app.

We have not made any recent changes, so this is quite a surprise.

What changed recently to cause this problem?

Please contact support@appsheet.com for help with this.
