I don't know if this is actually a bug, but selected map layers are not saved after exiting the app.
I open the app
select Clouds layer (instead of default Wind)
close the app
reopen the app
displayed layer is Wind again, instead of my preference Clouds.
If this is not a bug, it would be really nice to have this.
I'm using the latest (22.3.7) Android app.
Keep up the good work! :)
