In my Daily Challenge today, the map would not expand past it's minimum size setting.

Clicking the expand button (i.e. black arrow tilting up & left with white background) resulted in no visible changes.

I did some digging, found that pressing the "pin map" button worked as intended, toggling between visuals representing 'pinned' and 'unpinned.' I was unable to assess the functionality of the shrink map button, as the map was already at the smallest setting.

I refreshed the page multiple times throughout the rounds, and attempted to expand the map in every round.

Recreating this issue should be as simple as loading a round, opening the map, and attempting to expand it.
