Recently, and issue occurred in my previously-functional app using LinqToTwitter when authorizing a new user with a PinAuthorizer - after the user logs in, the pin momentarily appears on the screen, and then the browser redirects to a page that simply reads:
"This page requires some information that was not provided. Please return to the site that sent you to this page and try again ... it was probably an honest mistake."
I downloaded the most recent library and ran the Windows Phone 8.0 demo, and the same error occurs. But, if I use the link passed to GoToTwitterAuthorization on my desktop, it authenticates and displays the pin properly.
Any chance you can do some digging to see what could be causing this? Thank you so much for your help!
