every time starting Thunderbird I'm getting a window asking to convert read-only online ics calendars.
Since I only subscribe to the calendars (like holidays or sports matches), they are as a matter of fact read-only. So every time I uncheck the checkbox below and choose Cancel.
One link for example: https://calendar.google.com/calendar/ic ... /basic.ics
How to deactivate this check or accept this as read-only permanently? The query is annoying!
It says:
A check by the provider for Google Calendar has revealed that the calendars listed below
have read-only access to Google Calendar. If you want to provide calendars
with write access as well and therefore want to convert them, please select them below.
[ ] Always check
Convert / Cancel
