Do you now have a beta installed?
You were asked to sign a non-disclosure agreement when signing up for the beta program:
CUSTOMER SEED AND CONFIDENTIALITY AGREEMENT
OSX Beta Program FAQs>
The NDA prohibits you from discussing software beta issues here or anywhere else. The two documents above describe how to submit problem reports to Apple.
Issues with pre-release i.e. beta software should be discussed in the appleseed forums and not here. The majority of people here do not have access to the beta software and Apple themselves do not actively participate in these user forums.
You should also be using the Apple Feedback tool included in the beta software
Otherwise:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.

All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
