It appears all my calendar appointments before 2018 have disappeared. I suppose I have a link with my gmail account because of the required account setup, but I always entered all the events directly on the phone's calendar. Is there any way to restore the appointments?
Considering how many people seem to be having this problem, I would have hoped there would have been more than mere speculation at hand at this point. Fortunately, since it isn't as simple as "not on the cloud, all gone," the FORCED gmail account I had to have on my Samsung phone ensured they were actually backed up on my Google calendar. I was really hoping not to have to add another app to my already filling phone to get to my appointments, but for now, that will have to do. Thanks anyway.
This may be a bit late to help you. My sister lost all of her events on galaxy s8. i simply added an event to make sure her sync was working, after i entered the new event a screen appeared that stated you need to turn on notifications. i clicked the turn on button and puff the calender filled up with events. I hope this will help you
