Hi,
I'm using a CalDAV server, which supports scheduling described in rfc 6638. When I connect to this server from the desktop macOS calendar client (or any other Apple calendar client) everything works fine, however I am not able to see attendees availability when I want to invite attendees. The "Check Availability" button does not appear. However when I connect to another server (Google calendar) and want to invite attendees "Check availability" is there.
support.apple.com says that
You only see Check Availability if your event is on a calendar service that tracks availability, such as CalDAV.
My server is a CalDAV server, which supports scheduling, but still I can not see "Check Availability". Is this feature available for all CalDAV servers?
Thank you
