I have one Favorite added way back when. Now I'm unable to delete it nor add any new ones. When I select (click) a new location to add or enter Long/Lat in the search field the Favorite "Heart" icon never shows up to add to Favorites.

Thanks in advance for your assistance

Today (10/20/2025) The Air Quality 'widgets' are non-functional, presenting a display with a grid-like image but without the air quality info expected. .

Switching to some other layer widgets hides the "grid" but then it returns when selecting any of the Air Quality layers.
