I bought a lumia 2520 and keyboard about a week ago, I can usually log in without a problem. Once I am in and want to type on IE or word, I have to press and hold the key for it to type anything, I tried buying a bluetooth keyboard and that had the same issue. Microsoft, Nokia and the Verizon techs have not been any help. I have updated the firmware and tried restoring the tablet, am I missing a setting somewhere?
