The only calendar annoyance I've found so far is that I can't add attachments to my Proton calendar. Both Google and Microsoft Office calendars let me attach files. Sometimes, if I'm attending an event or something, I like to attach the flyer with details to my calendar event, so I don't have to dig through my email for the details. Right now, I can only type in a description to Proton calendar events.
Oof that should be a crucial feature to have.
