Ok so I made an acc for testflight and it says your account is waiting to be approved it's been like that for 5 days I need to beta test a game and I need to get in D:
So can you get into your dashboard then? If the dev has not released any builds yet, all you will see is a screen saying something along the lines that this device does not have any builds for it. And unless I am mistaken, the dev has to approve you for their testing as well, so it may be on the devs end and not yours.
Bro, you just gotta wait for some developer to send you an invitation or a build for a game! It's already been approved! Go to upcoming ipod touch games section and look for threads with beta testers wanted signs on! Then just apply by sending email let's say to email or pm!
Did you get email by deo, that you're asked to install build? Oh and could you show screenshots of Dashboard and the email if you got it.
Maybe you shoud still wait for the build. Be paient. I wait for several days too to have my first test. I'm very worried at first like you too, but now I get it.
