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)?

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

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.

@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.
