When in Edit more for an app, clicking the blue Share button in the top right:
...opens a modal with options for sharing the app.
Therein is a blue button that says "Edit" with a prefix icon indicating it's a link that opens a new tab. Hovering this button is a tooltip, "Launch app in editor mode":
(^ Excuse the redactions making the area around the modal look weird.)
The problem? I'm already in Edit mode. And I want to go to View/Read-only mode... which is what the button actually does when clicked. So there's no functional problem, this button is just mislabeled.
I recall this was actually a bug that got fixed not that long ago, with the button labeled "View" or something. But apparently it's regressed.
This happens in all of our apps.
