The ability to edit an event in the iOS app is no longer available. That is such an inconvenience, which impacts negatively the user experience. I know I can log in with a browser to edit events but that makes the steps to something simple as making changes unnecessarily long and cumbersome.
Great app but iOS widget missing!!
I love proton, have been a paying user for many many years now. Love the apps but really important for me to solve an iOS widget for calendar app. Thanks.
Dear developers
Please reconsider fixing the app from crashing. It does so every time I try to create a new event that is reoccurring.
Great
Great stuff! Any plans for an Apple Watch app?
Week numbers??
Almost there but I need week number’s before I can switch my calendar.
I shouldn’t be so difficult to implement.
Decent start, works fine
Works ok but needs more features, for one the app needs to be able to import ics from email, works ok on desktop. Also make it easier to securely share my calender with anybody
Works fine
Works just fine.
Missing week numbers, without it im not sure i ca switch at all.
Also missing possibility to ad events from other apps.
Wonderfull but useless
Love the idea of having a encrypted place where you can write down your appointments, useless bc I cannot share a calendar with my husband. I have a subscription, but apparently I need a much more expensive subscription for that feature, which I think should be a standard feature.
