Monica CRM - CardDAV & General discussion

Are there here people who use Monica?

I am already for years eying this app and I want to use it. But the main things holding me back is the lack of a good CardDav connection to my iOS and MacOS apps.

Also the app has been unmaintained again for some time; and I wonder if it makes sense to trust an app with my important CRM data if it might be abandoned sometime…

I was wondering if there are people here who actively use the app; how they use it and if they found solutions to the Dav issues of the app.
