Can not log on – Dynamic Study Modules Review

So some of you are saying so long as you have logged in once on the computer you can log in on the app!! I have logged in more than once in my computer and on my mobile phone and this app doesn't work. It keeps stating that my log in info is incorrect, this is simply not true!! This needs to be fixed as it a great tool to have access to at all times on our phones!! Please fix asap!!!
