FR - CalDAV support for Contacts.
I'd like to be able to manage my many TeamViewer contacts via my contact manager. Considering that I can currently manage them from Google (contacts.google.com), Nextcloud, and Microsoft (outlook.live.com/people) all in one place, I'm rather disappointed that I can't manage TeamViewer contacts in a consistent manner, especially considering that this should be enterprise-class software.
What happens if CRM usage were mandatory at an organization level? I'd have to dispense with TeamViewer Contacts entirely.
