Hi, I'd received an invitation for test flight, but first, i need to join their development team.
I'd received the email invitation for joining the team. Click "Accept Invitation", and prompt to log in. Success. But, I'd received "Cannot proceed with the request" message. Although, I'd try 2 different account tester.
When, I click, "Contact Us". This page appeared.
And I realize that, sometime, I didn't receive the invitation link although my teammate had sent it multiple times...
