I deleted a couple messages from the combined inbox, the combined inbox then duplicated messages and when a new message arrived, it was not displayed in the message pane.
As an example, I deleted the "Your Daily Digest' email from 9/15 but it remains listed in the message pane.
The new message, the Your Daily Digest is for today the 16th (as seen in the screenshot) isn't displayed.
This started this morning.
This is what the error log has
Is there something else I can run that will be more helpful?
