@Mario.Romero - Thanks for reporting and thanks for the support! Hopefully we can get this working for you 
Could you try changing the wsgi file from:
from dashapp import app as application
to
from dashapp import server as application
“server” is the instance of the “flask” server and that’s what PythonAnywhere / wsgi will expect.
If that doesn’t end up working, I’ll create an account with PythonAnywhere and see if I can get it working
