backup problem

[retoa]

Hello

I updated 4 Primes with the new CK, my own and 3 of my student's who have a Mac at home (I have 50 students with HP Prime and due to the Administrator problem they can not update their calculator in the school, I hope the most of them can do it at home...).

As the CK proposed it, I clicked on the backup button. The first time it always said there was a backup problem, by a second click the backup went good.
The restore went good for 3 of them, in one case there was some strange behavior, the calculator name was not updated and all the user variables were set to 0 (real).

Did someone else have similar problems?
