"Check Availability" button disappears in CalDAV clients

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

Same issue here.

Some Macbook air have it working and have had it working. Some other don't.

I was wondering if perhaps if you have more than one account that does scheduling, perhaps the Apple calendar, the caldav client has some kind of bug that does not behave as it should...

Did you solve the issue?
