So I am new to Sencha, and I built a very simple test app to pull in a few feeds and display some pages. I moved these files to my server and it works fine on the desktop Chrome but when I view the test website on a iPhone Chrome browser the bottom nav buttons are pushing below the viewport:

You can can test the above link in Desktop Chrome Browser vs iPhone Chrome Browser to see the difference. I cannot scroll up either to reach the bottom nav bar, it is stuck there. I do not want to send this to Apple to post, I just want to show my partner how it works. Any help would be most appreciated.
