Hi Eskimo, The issue was coming at the time of app archive from Xcode. I've solved this by adding "Apple World Wide Certificate." and Now after upgrading my macOS version from Catalina to Big Sur , My app is successfully uploaded to Testflight. But the build is still not showing in Testflight. Can You tell me the reason behind this issue please.... Regards, Ripa Saha.

Hello Eskimo, Testflight is the place where app is uploaded for beta testing. Testflight is also part of app store connect. My above issue is also solved. I think - app store connect has some issue that's why it was bit delay in displaying the build. Thank You Eskimo.

Is it Your macOS app or iPhone and iPad app?

Yes, download button comes instantly after generating redemption codes. Check whether You've generated the redemption code properly or not.

Check Your MacBook space and also internet connection. For latest version Xcode , Your MacBook's 50GB minimum free space required. If internet connection is not proper in that case also Xcode download freezes. Increase Your laptop's sleep time. at lease 8 hours .. If all of the above point is ok then - there won't be any issue in downloading Xcode.

I'm also got a same issue. Does anyone found any solution yet in this thread.
