With the latest version, every time I enter a key and secret (and confirmation password), it states that the API key is incorrect.

I have entered this multiple times, by hand, by emailing it to an account accessible on my phone and copy and pasting the key and secret into the relevant boxes. Nothing works, so all I can do with the app now is see the current price.

I have tried Windows Phone 8.1, 8.1 with update, and reflashed back to 8.0. Nothing will accept the API information, no matter how many times I recreate new keys, and no matter how many times I try to enter them. It used to work before the app was updated (using copy and paste from an email to myself containing the key and secret).

Frustrating!
