Pizza Party - Display fusion table in web viewer not working

the app works perfectly EXCEPT that it is not showing any content in the webviewer.

I used the original source.

And yes, inserting data works.

What can I do? Or does the app "works as designed"?

do you get a result, if you open the table url in a browser?

if yes, set screen scrollable to false, set webviewer height to fill parent and scroll inside the webviewer

Thank you! Setting screen scrollable to false helped. Rest was already set!
