You can't discuss the beta, you agreed to a Non-Disclosure Agreement (NDA) when you signed up to the use the beta. Use the feedback tool you got to report the issue. I don't believe there is a way to turn it off.

AbrahamMatar if u will find the solution please told me.

Nobody can post anything about it here because of the NDA.
