We cannot discuss Beta issues in these forums, as the beta is considered confidential and you are under an NDA to not disclose information about the beta in a public forum.
If you are a developer, you should have access to specific Beta developer forums you can request support from, otherwise, Apple offers no support for Betas or issues derived from running them. You are on your own when dealing with the Beta.
