[Bug] Cannot import contacts - "faulty contacts"

I want to import all my contacts from my Android phone. I have exported them to a vcard file.
When I import in NC (NextcloudPi 16.0.4), all 152 contacts are reported as faulty and none imported. Browser console shows:

Are there any messages logged in the Nextcloud log file?
Which VCard version are you trying to import?

Apparently the vCard version is 2.1 (from Android Contacts), so I guess that is the problem. Should be 3.0 or 4.0.
Need to find a converter.

Problem solved: instead of Contacts on Android, I exported from Google Contacts (web), and that vCard is version 3.0, so the import to Nextcloud Contacts went without errors.
