I uploaded the app to App store connect and wanted to distribute the app for testing. The current status for my app under testflight is "ready to submit". I added a few tester under internal testing group. They all received the invitation, and succefully accepted and has the app in their testflight.
However, when they are trying to download, it shows "The request App is not available or doesnt exist".
My developer account is in China and the tester's apple account is also in China. Why does this happened? How can i slove it?
Meanwhile i tried to add testers to external testing group, However, every time i tried to fill in testing info, it show "There was an error processing your request. Please try again later.". I cant submit my app for external testing. Is really confusing.
Thank you
