An update to OC 8.2.1 solved it for one device, but not for another. An update to davdroid 0.9.1.2 solved it for the other device. So not too sure what the issue was exactly.
Error because received VCard with not exactly one VCARD
At the log I’m getting lines like
[error] Received VCard with not exactly one VCARD, ignoring b1c5e8a83b8da48fe0dfc6d654307ad494b1b12f
The VCard that it received is
BEGIN:VCARD EMAIL:firstname.lastname@example.org FN:Foo Bar N:Bar;Foo UID:b1c5e8a83b8da48fe0dfc6d654307ad494b1b12f X-CALYPSO-NAME:b1c5e8a83b8da48fe0dfc6d654307ad494b1b12f END:VCARD
If I have only one contact in my agenda DAVdroid sync it without problem but not with two or more contacts.

@raniere did you find a solution?
