Awesome when it works, about 50% of the time... – TestFlight Review

The issue is with the redemption code, when a user first downloads TestFlight it emails their Apple ID a code. If they don't use it within hours it expires and there is NO WAY to send them another one, so that beta user is dead. Three calls into Apple, have not found a support person who knows the first thing about this yet but will keep trying. Funny, they keep saying to call the app developer, which is Apple ? Hope they improve because it is really useful...
