iOS 9 Public Beta

I installed the public beta of iOS 9 on my iPad mini, only to be very disappointed. Half the features I was led to believe would work, won’t. As I have a first gen iPad mini.
Now onto the crashing apps. I’m trying to report this through the fedback app, only can’t sign in. I have a sneaking suspicion Apple got more then they bargained for.

Releasing a Beta with so many flaws, not even fit for public beta testing this should have been a closed beta test.
