I side loaded Mobicip on my daughter's Kindle. At first, when she would click on the Silk browser icon the Mobicip passcode screen would come up and I would just type in the passcode and she was good to go. Now, the only thing that can be entered in the passcode space are numbers. The passcode we're using is a combination and so she can't access the web. Can you please give me some direction as to have to fix this problem? Thanks!
