yeah I already looked for something in the release notes, but there's nothing about caldav

hi bydict, are you using sabre/dav as caldav server? I tried what you said, but my url was already in the https://abc.com/ form, no relative path needed... I tried some different combinations, based on your answer, but nothing seems to work... We need help from apple, but it seems impossible to get in touch with them

Hi Igor11 and thank you for your comment. Yes, Apple should definitely look into this issue. I tried contacting them on developer and customer support and feedback channels, but they have not yet replied...
