I sent an invite email invite to an external tester. All it has was legal notices and links to legal notices.
At the end of the email there is a 6 character string that I thought was the passcode, but the last 4 characters are numbers, so it doesn't work. Testflight only accepts letters for the code.
This is the first time I have used testflight and I have no idea what is wrong and I can't deploy my app on any iPhones because of this. My app is waiting to be deployed from TestFlight.
