Calendar Sync turns off by itself[SOLVED]

Hi,

Question about android calendar.
I set up my calendar to be synchonized with my google calendar and it works perfectly. I set my android calendar to be automatically synchronized and it also works fine.

The problem is that I don't know why but after a while, the Automatic synchronization turns off by itself and I always have to re-check the option.

Do you know the reason?

Thx

 

Ok, I finally solved it, I use Setting Profile as profile manager and I don't know why but one of my profiles had one of its settings to turn off the auto sync data....
