One major problem

I’m new to proton. I just signed up and am starting to migrate my email to proton. I am trying to use the calendar but I’ve run into an issue. If I receive calendar invites in my email that are an attachment (such as an ICS file), there doesn’t seem to be any way to add them to my calendar. From the proton mail app there is no “add to calendar “ button. From the calendar app there is no import that I can find which allows you to import a downloaded file, and in iOS when you try to use the “share” button the calendar is not an option. This means the only way I can find to add some invites to my calendar is to manually enter the information. Ideally an “add to calendar” button should be available from the mail app, and a share extension should be available so you can receive a file/invite into your calendar.

On the plus side: My wife and I are both migrating to proton, so it’s nice to be able to share the calendar with her and both of us to see the same events. I’m still new so as I use this more I can get a better opinion.

Hi! Thank you for your honest feedback. Unfortunately, at the moment, it is not possible to accept/decline calendar invites through the Proton Mail iOS app. Currently, in order to accept or decline calendar invites on an iOS device, you need to access Proton Mail through a web browser at https://proton.me/mail and open the invitation from there.

This option has been requested already and we have added your vote to it as well.

Great, Secure Calendar!

Really enjoy this calendar and its security 👍 There are a few features that I wish would exist though. I’d appreciate a search option to be able to search for an event, instead of having to go through each Day until I find it. I’d also love it if it would remember events I’ve created in the past, so that it could auto-fill in some of the specifics for frequently added events (ie. the event location, notifications, which specific calendar). Lastly (and I think this might be a bug), I’d like it to remember how long I’ve set the duration for specific calendar events to be. For example, in settings, I’ve set my “work” calendar’s duration for events to be 120 minutes, but, no matter which calendar I select, it defaults to 30 minutes so I have to change it manually.
*I generally use the app, so some of these may be available on a desktop browser, and if so, please let me know!*
Overall, I like this calendar a lot, and offer these desires as I’d love to see them come into fruition to make my Experience more easeful. These are really just conveniences, but ones that I became used to when I used the apple calendar before. This is now my sole calendar and I’m very grateful for it! Appreciate all the effort that has gone into creating it and the security it offers ♥️

Totally unserious app

Doesn’t function by itself. They don’t allow you to change the timezone for the app from GMT +0 Afrikaans unless you go login in through their desktop or web app, where they let you change it there. If I travel, I have to login into the web client each time to manually change the time zone of events to the appear in the local time zone. What’s wild is when you create the event, it asks you what time and time zone you want to input for this specific event but then converts it to GMT +0 after you hit save. I can’t schedule a reoccurring appointment before noon at the 30 mark. If I try to make or edit a reoccurring appointment at 11:30, 10:30, 7:30 etc I get “Events synchronization error: Response error.”

Every time you install an app vs use a web app, you have less control over the information they access and to me it makes no sense to give up meta data about my device for what essentially is just a mirror for the web app. I only switched to Proton a month ago, but who knows how long it’s been like this. When people can’t schedule appointments in their calendar at certain times, why are the updates about anything other than fixing basic calendar functions for this calendar app?

Hi! Thank you for your feedback - we've shared it with the team. Changing your time zone is currently possible on the web app at https://calendar.proton.me/. The changes reflect in the iOS app as well. Nevertheless, we understand the need for changing the time zone in the app, and we'll add your +1 to help the team prioritize future improvements. Feel free to contact us at https://proton.me/support/contact if you have any additional suggestions.
