I am on the latest version of Byzantium. Suddenly yesterday after clearing out some files to fix an issue with low disk space on the L5, upgrading and then rebooting, contact names are no longer visible in Calls or Chatty. I have rebooted again, but problem persists. My Nextcloud contacts still showing in the Contacts app though.
Edit: after the last reboot, contact names are visible in Calls, but still not in Chatty.
Any ideas about what could be wrong?
