"Till this is fixed, here is a solution by using transporter." Thank you very much!! @metehandemircioglu Your solution worked straightaway and is very fast. I reckon I'm going to be using Transporter from now on and stop wasting time with problems trying to upload from Xcode

I'm getting this on all my app submissions now. Still not fixed for me

I opened TestFlight this morning and the new builds that weren’t there yesterday are now showing up. Also the ‘What to Test’ notes are showing up too, so looks like they've fixed everything 😃 👍-1F3FB;

Same issue here in Greece. I've just spent several hours uploading 14 apps and found the issue that none of my internal testers can update to the latest build through TestFlight. Even though I expired the previous builds, TestFlight is still showing them as available and if you delete them from the device you are still able to install these expired builds.Uninstalling and reinstalling TestFlight doesn't fix the problem.I added the “App Uses Non-Exempt Encryption” key to the Info.plist as outlined in the link below, and increased the build number before rearchiving and uploading to App Store Connecthttps://developer.apple.com/documentation/security/complying_with_encryption_export_regulationsNow the new builds show up in TestFlight, however they get published immediately so you don't get the chance to add the Test Information in the 'What To Test' box until after it's published, and in TestFlight it shows "No test notes" even though I did type in and save Test Information.
