Mosaic Bug ?

Hi,

I tried Mosaic for a week and it seems to be the app I'm looking for.

However, I think there's an important bug...

I'm working on a MacBook Pro 15 on Mac OS 10.14.6

Sometimes in standalone, sometimes connected to an Ultrawide 21/9 screen and a 22" monitor.

I've created multiple layouts and integrated them in groups. My layouts are attributed to specific monitors and this is where the bug comes in.

When I open Mosaic, my groups aren't working because when I go to the layout in the preferences, it says that the monitor is not connected, even if it is...

Is it a normal behaviour ?

I hope to have an answer from you, because I can't buy an app if it isn't fully working...

Thanks in advance
