I have used and loved this calendar for years but lately it's been driving me CRAZY. I have repeating events for my work schedule but sometimes I need to come in a bit early or late depending on the day so sometimes I edit these events. But I always select THIS ONE ONLY but lately if I edit any recurring events it will edit the one I was trying to edit but then delete ALL INSTANCES of that recurring event both from before and after that one event I needed to edit. I am FURIOUS.
