After the last update I have a problem with the recurring events. Instead of once a week, the event was now in the calendar every day. I have deleted the recurring event and created a new one. Now is the recurring event several times a day in the calendar instead of once a week.
Sorry, it's hurry for me to solve this problem,
Addition: I have just seen that it is presented in the calendar as described. But when I click on an event in the calendar, I get a list with the correct dates of this event.
