On geogebra.org: Published file acts differently than opened file
I wrote a GeoGebra file for pupils to practise identifying primes. If you get an answer false/wrong, a red/green flash feedback text appears for a short time. It all works fine (GeoGebra Classic 5.0.583.0-d on Windows 10).
When I upload the file to geogebra.org, the red/green feedback texts are not shown in my browser. But if I click in my browser on "..." --> "open with App", all works fine again (tested with several browsers).
I know the file is kind of complex to look into it. But my question is more general: Why does the "applet view" act differently that the "open with App"-view? What can I do to get the expected behaviour?
