The Ask setting does prompt me but clicking “Allow this time” just ‘refreshes/reloads’ the prompt (I click it and the prompt blinks off then right back on again). I also describe the behavior in my initial post (just below the screenshot), if that helps: If you look at the screenshot, you can see the prompt to allow but clicking either option doesn’t work. It used to work fine in the past.
I hoped this is something related to this being a paid/commercial Google account but testing on a ‘free’ account with Brave resulted in the same issue.
Edit: @Mattches this should help:
