These problems are occurring with more than one Gmail account. In two cases when a new sync was attempted, only 140 out of 1200 contacts were brought into a Z30 from Gmail. On a Z10, with a different Gmail account, I am getting the message: An unexpected problem occurred with CardDav:Gmail. CardDAV is an open-source protocol based on WebDAV, which is specially designed for synchronizing contact databases. The client-server protocol enables digital address books and contact details to be stored and shared on a server. But apparently CalDAV support via the default Gmail icon was added in iOS 6. Apple’s automated setup for Google accounts on both OS X and iOS only configure Gmail & Notes (via IMAP), Calendar & Reminders (via CalDAV), and Messages (via XMPP). CardDAV must be added via the “other” method as described in the post. Apr 14, 2021 You can view and manage your contacts using Google's CardDAV protocol. Contacts are stored in the user's Google Account; most Google services have access to the contact list. Google has decided to change the authentication mechanism for their CalDAV calendars to OAuth, which required some changes in Lightning to accommodate. Due to these changes, the URL to access the calendar has also changed. The old endpoint will stop working after September 16th (today!). This affects only Google calendars using CalDAV protocol.
Recently Google announced that it would no longer support Microsoft’s ActiveSync for syncing Google services — Gmail, Calendar, and Contacts — with new mobile devices. Current users would not be affected but newer user would not have the option.
This will have an impact on iPhone and iPad users who are used ActiveSync services for push notification. However, Google does support standard open protocols — IMAP for email, CalDAV for calendar, and CardDAV for contacts — for connected to it’s services. iOS users aren’t left completely without connectivity options. iOS supports these options natively and they are easy to configure.
Launch the Settings app and navigate to Mail, Contacts, Calendars. Under the Accounts section tap Add Account.
From the list tap, Other.
The Calendaring Extension to WebDAV (CalDAV) is an Internet protocol standard allowing a calendar client to get access to scheduling information on a remote server. iOS supports CalDAV natively and setup is relatively easy via the Settings app.
In the Calendar section tap Add CalDAV Account.
In the server section enter google.com for the server. Use your full Gmail email address for the username. If you have enabled two-factor authentication on your account enter the application specific passcode instead. Tap the Next button to complete the setup.
That’s it for calendar. Now for Contacts.
The Card Extension to WebDAV (CardDAV) is an Internet protocol allowing an address book client to exchange contact information with a remote server. iOS supports CardDAV natively and setup is similar to setting up CalDAV.
In the Calendar section tap Add CardDAV Account.
In the server section enter google.com for the server. Use your full Gmail email address for the username. If you have enabled two-factor authentication on your account enter the application specific passcode instead. Tap the Next button to complete the setup.

Now for the last piece.
Internet Message Access Protocol is an Internet standard protocol used by a Mail User Agent (MUA) to get access to email on a remote server. iOS natively supports this standard.
In the Calendar section tap Add Mail Account.
Sync Carddav Gmail
In the Incoming Mail Server field enter imap.google.com. In the Outgoing Mail Server field enter smtp.google.com. Use your full Gmail email address for the username. If you have enabled two-factor authentication on your account enter the application specific passcode instead. Tap the Next button. You may be prompted to save the settings. Tap Save and then make sure the Mail and Notes switches are on before tapping Save again. Your account is now setup.
