Calendar notifications fail S Planner

Question

I have a Samsung S6 Edge plus.
Android operating system 6.0.1
I believe that since the last update of the system, I fail the notifications of the calendar S Planner. And the Google Calendar.
If I write an event so that it notifies me today, for example in an hour, if it does, but then another event scheduled for the day after tomorrow, it does not let me know. It's like he's stuck. If I plan another test if you let me know, but the next ones already scheduled do not.
I do not have any antivirus installed now.
I would like someone to help me solve this problem.
Thank you very much.
Sincerely

I imagine you have seen that the "synchronizations" are well placed ... where do you create the event on the phone or on a pc? I use the calendar of google and in the mobile the android and it goes well ... tell us

The same thing happened to me and I tried everything, until I had to reset to factory values and it was solved
