There is a really strong reason why the Proton team should bump this further up the priority list. It's because whenever I have to apologise to my friends and colleagues that "my calendar is broken", it's an opportunity for them to learn that Proton Calendar is not very good.

Even if that's not true - that's the impression everyone is going to get.

I found another quirk yesterday—when I am an invitee on a recurring series, if the sender cancels an instance, there's no way accept that cancellation and get the event off my own calendar.

Though at first the event displays struck through when the sender pushes out a cancellation, when I went into the event to 'accept' the cancellation and get it off my calendar, Proton instead seemed to step *backwards*, removing the strike through from the event so it looks like just a normal calendar event again.

To remember the event is cancelled I had to add a second event in the same slot that says "NO [event name], CANCELLLED".

This is baseline calendar app functionality, and needs to get prioritized and sorted soon else I can't keep using the product and living with limitations that simply should've been fixed from the start.

Yes, I want to be able to decline or delete a single event within a recurring series of events. Not having this feature has been an issue for me.

PLEASE - we really need this feature for our remote team. it makes it so hard to flexibly react to changes in our schedules. it is very frustrating, without the option to modify a single event in a recurring series, we have to manually try to let everyone know that todays meeting is moved to tomorrow and send out an additional meeting for tomorrow, while the slot for today apprears as booked when it is now actually free. very frustrating with remote teams that are hard to reach

This is very painful to not have. Trying to use Proton Family and we have to modify single instances of things all the time. Creates massive confusion not having this.
