@App Store Connect Engineer Still getting "Internal Server Error" on opening of link https://testflight.apple.com/join/u1953sBd This happens on multiple devices and users are complaining to me as well about the TestFlight link not working.

Please fix it as there is no way for me to read stack traces now. App id 1462943921 with iOS version 1.20.0 in TestFlight.

Same issue here. @douwe @flmat see also: https://developer.apple.com/forums/thread/700051

Hi Quinn, TestFlight is now supported on macOS. Could you please confirm whether TestFlight is supported for macOS apps built without Xcode that are signed manually (e.g. a JVM app)?
