Hi! I am trying to install Mobicip on a Kindle Fire and can't get past the "install" screen. As it's not available in Kinde's app store, I had to sideload it, which I successfully did on my oldest childs tablet with zero issues. It opens the permissons page and asks if I want to install, but nothing happens. I can either "cancel" or "install". Only the cancel option works and closes me out. The insall option does nothing. What could be the issue?
