Offline Items? How do I remove/remediate them?

Hi Dave, thanks for the response! On Mac desktop I get a banner which says, "Some changes could not be synced with your other devices."

In my case, the single 1Password item with this issue was deleted from my vault a long time ago and therefore it hadn't been changed. Now it shows up only in the 1P Mac desktop app, not on other devices (which are all updated to current versions).

Edited to add: I logged in to my online vault and clicked on "Restore" from the Deleted Items. Then I deleted it again using the desktop app. So far the sync issue seems to be resolved.
