To elaborate on this, the reason why you can't select Proton as the default calendar is that the calendar is managed through the app. In order for, at least on android I don't know about IOS, the calendar to be able to be selected as default Proton needs to open the calendar to be able to be signed in through a "less Secure" platform such as the phone instead of through the app. All that being said I 100% support this change. Proton please consider this!
