Pairing KOrganizer with apple calendar

I’ve been attempting to get this process to work for a while now. I have attempted to follow this post, but when I attempt to add the pX-caldav.icloud.com, I get an HTTP 400 error. I’ve attempted to use the link given by the calendar instead as well (webcal://p39…), but that did not work. I have attempted to change the access protocols, but that also did not work. I attempted to do this while the calendar was public and while it was not, and that did not change anything.

What am I missing or doing wrong? I appreciate your help.

PS. I saw in a few posts that KOrganizer had a bug where it wouldn’t be able to fetch the calendar, only post to it? Is this still the case? If so, are there any workarounds for this issue?
