@sgilbert ...
Thanks for sharing that screenshot. Very interesting. I also see "Canvas LMS" on my tab...just like you do. The only recent updates to the Inbox that I see documented are listed here:
Canvas Release Notes (2023-07-15) - Instructure Community (canvaslms.com)
But, I don't see any reference to the "Canvas LMS" label that is displayed on our tabs. Maybe this slipped through the cracks as undocumented...or was an unintended change??? Who knows.
Maybe it would be good for you to submit a ticket to the Canvas Help Desk folks about this so that they can look into it a bit more. I agree...it would be nice to have this back to "Inbox" so that it's consistent with other labels when you click on those areas of Canvas.
How do I get help with Canvas as an instructor?
Hope this helps!
