Same from India. Previous build was working fine and I made some minor changes and now the uploaded build is not showing in testflight.
I am experiencing the same issue, I couldn't find the API keys tab under users and access, I have tried this URL - https://appstoreconnect.apple.com/access/api But is redirecting to users page again. Someone please help to find a solution. Its very critical for us because we are in the stage of final release and we couldn't automate the build process due to this issue.
