When I try to install the iOS 9 Beta profile, it fails and gives me the following error message - "PROFILE INSTALLATION FAILED" - The UUID for the profile "iOS9 Beta Software Profile" is not unique." it's actually failed a couple of times while i was trying to install it and somehow i now have the feedback app on there, despite being on ios 8 and no profile installed! This is on my old 4S (not installing a beta on my main phone, i don't want to risk it). When i got the 6S set up, I restored its backup to the 4S to get it set up to my needs quicker - could this be behind it? Any ideas?
