According to the latest information, the second beta of iOS 10 can eventually block the Apple ID being used if we use two - step verification.
Apparently, after the Apple ID is blocked there is no way to unlock it , but fortunately, Apple has recognized the problem and has confirmed it is working on a solution that will arrive as quickly as possible.
Thus, if you have installed the second beta of iOS 10 as sitting at the moment it is disable two-step verification, but on the other hand, if you have not experienced the problem is most likely not will affect later.
In short, although it is indeed a very serious problem and can be very annoying to who gets them, keep in mind that this is a beta, so installing it we run the risk of this type of failures.
Do any of you have been affected by this annoying inconvenience?
