I prefer to use InDesign in the application frame but since the Update I constantly getting over the new "Publish Online" Button, triggering the big annoying overlay which is blocking the buttons I wanted to reach:
I don't use the online publishing feature so I'd like to get rid of it but I couldn't find any way to do so. Also I don't know why the overlay gets triggered by a mouse over unlike everything else in the GUI which seems like a strange interface design decision.
Edit your preferences under technology previews. Turn off Publish Online.
Thanks John Mensinger and BobLevine!
