Of course, the problem is much higher for users who did not make the necessary backup before updating.
However, as it seems on Twitter, the problem is not observed on all devices.

Users, however, continue to report the problem, so maybe Apple could not even fix it as it claims.
So if you need to upgrade your operating system to iOS 10 today, it's a good idea to make a full backup before you start.
However, the update I made to 6 Plus OTA from 9.3.5 went fine with no problems.
