Hi @mozibrand ,
I have a similar problem from my app.

My solution : I passe args (like filters) to screenProps of AppNavigator (a "Reduxify" navigation).
Maybe you can take example to resolve your situation ?

Else, have you got found any solution at your problem ? i'm interesting by any suggestions
