To zoom in using my mouse wheel, I have to hold down shift, and then it zooms in the opposite direction to how it works in Google Maps (Firefox 64.0 on Ubuntu).

I also can't drag the map around or click on any items on the map. Really inferior experience so far.
Did you find a way to switch back to the Mapbox maps?
