To synchronize your Proton calendar to your Vyte account:
Go to your Vyte settings
Go to your calendar settings
Click on "Add a calendar account Pro”
Click on "Read only ICS calendar Pro"
Enter the URL of your Proton Calendar
Here’s how to find the link to your calendar in your Proton account: https://proton.me/support/share-calendar-via-link
Vyte can now read your Proton calendar to see when you are available or not. To write to your calendar, Vyte will send you calendar files (attachments) that you can add to your Proton calendar.
All your Vyte appointments will now appear in your Proton Calendar. You will also receive an email confirming the appointment. This email includes a calendar attachment—simply click on attending: “yes” for the appointment to appear as confirmed in your calendar.
⚠️ Important: The Proton Calendar integration with Vyte does not include “option” appointments. This means that if your clients suggest several possible dates based on their availability and yours, these optional dates will not appear in your Proton Calendar. Only once you confirm one of these dates will it show up in your Proton Calendar. The same applies if you create an event in Vyte and send several proposed dates to your clients: the optional dates will not appear in your Proton Calendar—only the confirmed one will.
7. Check the "Show as busy" box for each sub-calendar in your connected calendar whose events should be marked as unavailable on Vyte (Learn more about the "Show as busy" and "Display to me" options)
8. Don't forget to save your changes 😉
