OAuth Redirects issue in TestFlight for Google Drive/Dropbox Integration

I’m developing a mobile app using Bubble.io, and we’ve wrapped our web app for iOS. One of the key features is importing and uploading audio files from Google Drive and Dropbox. However, I’m facing an issue with OAuth authentication during TestFlight testing.

After users log into Google Drive or Dropbox and confirm access, they’re directed to a white page that says “Verification complete,” but nothing happens afterward. When they close and reopen the page, they’re prompted to log in and go through verification again, suggesting the redirect isn’t being handled correctly.

This feature is critical for our app, and I need to ensure it functions properly before submitting it to the App Store. I’ve read that redirects might behave differently in TestFlight compared to a fully released app, but my development team and I haven't been able to resolve the issue.

Does anyone have insights into whether this problem might be resolved upon official release, or are there specific steps we should take to fix the redirect handling in TestFlight?
