Same here. Most prob because everyone is trying to download it at the same time and apple servers can't cope.Anybody else having issues downloading the final version of 8.4 with the PB2 installed? Mine has been stuck on update requested for an hour and 10 minutes now. Gears aren't moving in the icon either.
Just go back to the beta website and re-install the beta profile.I've been having the same issue. Thanks for the solution guys!
Dumbs question: I've been a public beta tester since they launched the iOS public beta program. I actually didn't request it; they just invited me. Deleting the beta profile won't prevent me from taking part in the iOS 9 beta will it?
