Error setting up a nanoflow button in a native app

Greetings, I was following the learning path , build a native app and using mendix 8.1.0 and eventually I bumped into this error message. I have a normal button with the action call a nanoflow, in a mobile page but I get the message error saying that I am using this action in a web content. What am I missing?

Is that mobile page perhaps being called from a web content page? Or accessible through navigation/layout from a web content page? In that case, this error will be given.


After reading your comment,  I decided to analyse the nanoflow.

After removing activity by activity I found where the error lied.

My show page activity was the problem,  it was there calling a web content page.

Thanks, it was exactly what you said.
