Bad Proton platform interaction with ICS email attachments
Proton Mail often fails to present UI controls to accept/decline calendar events.
This happens for about 10% of ICS attachments, depending on the service that generates the event data.
The Proton Calendar website permits these attachment files to be uploaded and accepted.
The Proton Calendar mobile app, such as for iOS/iPadOS, fails to support ICS file uploads.
This causes unnecessary friction for mobile users.
Please fix the mobile Proton Mail and Proton Calendar apps to handle the very same ICS data as the Proton Calendar website.

It's also because there are several formats for calendar events. ICS is commonly used by Google Calender. Proton Calendar should convert this in a way that it can be used easily.
