Bing button didn't work on Edge Dev

[rreneissance]

I remembered it clearly that 2 days ago I had this sidebar with Bing & other buttons on it, it worked properly. But today it's gone & I can't click the Bing logo on the upper bar either. 

Device Mac M1.

same here, the bing side panel button is disabled in full screen in mac os 12
but if you go out of full screen it is enabled again

@abuasar I see. yes the button worked & the side panel showed on non-full screen mode. Thanks.

Once I went back to full screen mode, it's unable to click the button & to hide the side panel.
