I am a proton drive subscriber at the 200 GB tier -- this fits my needs as a regular email user well. I haven't been a digital calendar user in the past, but I need to start using one, and have been comparing different apps. I really like the format of the Proton Calendar, and I want my calendar app to be encrypted for privacy reasons... but I am so frustrated that I have to upgrade for color coding in the calendar. This is a really basic feature and I'm not going to upgrade to use, and to get around it I have to use two different calendars so that color coding shows up. I think that color coding should be considered a basic feature that should be available to any paid subscribers. Thank you!
