Unable to submit build for testing!

Hi everyone! I am experiencing this issue:

This build is using a beta version of Xcode and can’t be submitted. Make sure you’re using the latest version of Xcode or the latest seed release found in What’s New in App Store Connect.

I have Xcode 12 beta on my Mac and have archived the app from there. I was able to submit the build for internal testing but it gives me the issue when I try to submit for external testing!

Same here - any insight?
Why don't you clean the build folder, re-archive it, and try again
(They support Xcode 12 beta in TestFlight now)
