Storyline 2 for Android

Hi, I think I seem to be experiencing a bug when testing a Storyline presentation via Android phone. I built it in Storyline 2. I was playing it with the Android native browser. It is okay in the Chrome App. I had the Articulate app installed too. The issue seems to be when you revisit the Storyline, it seem to add content from other slides. It also seems to add in a bit of colour similar to that of the search item button hover. Has anyone else experienced this? I'd be grateful for any help. Thanks Jenny
