Do you think it is possible to get some more information? Which version of Mapsui? Which zoom buttons do you use? Such things would be helpful.

Xamarin.Forms with mapsui 3.0.2

I am clicking on standard butons that are overlayed on map (+ and - icons)

HI, I am getting unhadled error when clicking on zoom/unzoom after I switch to offline map.

What does "after I switch to offline map" mean here? Can you explain what kind of offline map you are using?
