Currently, when you host a party as a game master, and players are scanning for something on the map, we're not seeing the map as they are. We extensively tested this, and it was always one zoom level away (zoomed out). You can find an example in this video: https://www.youtube.com/watch?v=LHxW3HWZyO8&t=8354s - it seems feneb is scanning for nothing, when in reality he's just zoomed in one level more.

I understand it may be hard to make this perfect because of different device sizes, browsers or whatever, but I feel like adding +1 zoom level as the default one would fix the issue in over 90% of cases.
