Form follow-up type & Tokens breaking
We use tokens to assign the external URL follow-up page on our forms (points to a PDF in Design Studio). We've done this for nearly a year. Within the last 3 weeks or so, we have found that the tokens are not working with certain browsers - including Internet Explorer and Firefox. Chrome also did not work on Windows OS machines. When clicking "submit" the visitor is not redirected, though it will trigger error messages. When I insert the exact URL in the external follow-up, it resolved the problem.

I know that tokens completely quit working recently, but was supposedly fixed. Not completely, for us anyway.
Is anyone else experiencing this?
