[Evolution] How to troubleshoot Google contacts not refreshing?

[Len Philpot <lphilpot01 gmail com>]

Evolution 3.28.5 (Xubuntu 18.04)

GMail via IMAP is working fine and when I initially set it up, my Google
contacts on the same account came into the address book OK. But at some point
(not sure exactly when) they stopped updating in Evolution.

I have it set to refresh hourly and I've created test contacts which
successfully propagate to other devices using Google contacts. There is no
indication of error from Evolution, no messages, alerts, etc. But even after
manually refreshing, new contacts never show up in the address book.

Any pointers on where to start troubleshooting this from an Evolution
perspective?

Thanks.
