I'm testing a mobile app on TestFlight, and during OAuth authentication with Google Drive and Dropbox, users are redirected 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 verify again.
I’ve read that redirects might behave differently in TestFlight compared to an official release, which is why I’m wondering if this issue might resolve itself upon release or if there are specific steps to fix the redirect handling in TestFlight.
Any insights?
