Apple Calendar event reverts to New Event
On my Macbook Pro (running Big Sur 11.2.3) almost every time I enter a new event and put the details in and then move off the event... it reverts to "New Event". This does not seem to happen on my iphone or ipad if I input the event there. But I am losing valuable details of what I have entered at times. Is there a fix? Any suggestions?
MacBook Pro 13″, macOS 11.2
