Store.cloudphotodb could not be synced message?

After using WD Sync with a My Cloud for several months with no issue, I have started to get the message store.cloudphotodb could not be synced every few minutes. I use a MacBook Air.

I did a Google search for this message but it did not return any results. I tried repairing my Photos file, restarting everything but no luck.

Any thoughts appreciated!

Thanks in advance-


Perhaps it would be best to contact WD Support about this. You can do so over the phone or via E-mail.
