Anybody having a problem installing the Soft Token on their iPhone? I follow the instructions but after I paste in the code to activate it I get, "This identity cannot be activated on an unsecured device." Called the help number and they were useless, "Must be a problem with your phone."

Anyone have any ideas (other than, "it works OK on my phone."

Specifics are: iPhone 5C, ios 9.3.1, yes I have a PIN to secure the phone.

Any help will be greatly appreciated and I will forward anything that works back to the help desk since, apparently, I wasn't the first caller with this problem.
