app doesn't support Samsung Dex

[itsvarun]

Some apps like marrow doesn't support Samsung Dex/ screen mirroring, 

any idea about how to solve the issue?

It might be a limitation from the app's developer. You can check with them to be sure. Dex doesn't allow or deny an app. Netflix and prime video do not work with Dex mode either.

You can't use marrow app anywhere other then mobile or tablet.  

Kuch b karlo . I tried all measures 😂
