Calendar reminders are not displayed

I am testing the current eM client version.
Unfortunately, I noticed that the calendar does not show reminders for upcoming appointments while the program is active.
Only when I terminate the program and then restart it again, the window is displayed with all missed appointments.
Do I have to activate any settings for the reminders?

Thanks for your help.

I am having the same problem.

Anyone else having this problem? I need the reminders to work.

It looks as if only we both had this problem. But I can’t hardly believe that.
