I have a splash activity in android who only shows a static image (as a style) and then moves to the main activity who "starts" the forms app, then I have a splash viewmodel who shows the same image plus a loading bar and in that viewmodel I chek the user is loged, download the settings, etc...
So I finally decided myself and started the meetup group https://www.meetup.com/es-ES/AlicanteMobileDevelopers to try to create a Xamarin comunity in the SouthEast of Spain.
I was and active member of the Alicante University .Net Club, and my experience wasn't as good as I expected, so I hope this time works better.
Please give mor info about the error, were it happens, what code do you have, full exception log.

If you subscribe to messaging each time you see the screen, you should unsuscribe each time you go out. If not you would duplicate the effect.
Implement the subscription and test change screens (if have), and sleep, stop, resume etc to see if in some cases the messaging is called more than once each time.
