Unfortunately, I don't have any help to offer, but I did want to let you know that it is possible to install on Android from Chrome. I'm replying from mine right now.

Clearing browsing history sounds like a good first step if you haven't tried that yet. Good luck getting it figured out!

If you can't install it, try to do it with the Samsung browser, it doesn't matter if your device is Samsung or not

Correct me if I'm wrong, but this is designed to work like Apollo, an iPhone app.
