Some apps are just stupid!

I install a new app. I try to log in to it and create an account. I get sent an email confirmation as part of the setup process. Then I get the email in my inbox and instead of 'confirm your email address' it says 'cannot find account associated with the email address' that I just put it and the stupid app won't actually let me make an account.

WTF?

I will try all the usual stuff like cache clearing, resetting the app, etc. but so far none of that's made any difference.

Frustrating but clearly the app doesn't want me.. I'll move on with my life now... 8-)
