Howdy. I'm pulling my hair out, trying to get my Mac's Contacts.app synchronized (and stay synchronized) with the contacts in MAIB's Nextcloud. I really like Apple's Mail.app as a mail client, which means I am dependent on Contacts.app as an address book. I have found, at least since v.0.22 I think, that the contacts in MAIB show up in Contacts.app upon an initial setup when using the nifty mobilconfig file provided by MAIB, but after that, there is no synchronization (that I can detect).
All appears to be working great with my MAIB/Nextcloud contacts including 2-way synchronization from the CardBook plugin for Thunderbird Mail on Linux and macOS -- it's just the Contacts.app on macOS that is being stubborn.
I've tried manually configuring the CardDAV connection and reading up on Nextcloud's documentation and troubleshooting pages -- as of yet with no joy.
Has anyone made Contacts.app on macOS work properly for 2-way synchronization with MAIB's Nextcloud?
I am happy to post screenshots or plist files or whatever might be helpful, but I am not sure where to start. Thanks for any input!
