Oh gotcha, I see what you’re doing. Samsung Calendar (I use the S24 Ultra) has 2-way syncing with GCal. Everyone else is on iOS and they all have Google accounts so GCal was the easiest way to handle it.

I have shared calendars with family and friends that I need to keep using.

I want to make the jump from Google apps but I can’t because I use GCal heavily and Proton Calendar doesn’t (yet) sync to GCal. I can enter in something in GCal and it’ll appear in Proton Calendar, but I can’t enter in something in Proton Calendar and it shows up in GCal. Hopefully they add that soon.
