We are seeing the same thing. Unfortunately your workaround didn't work for us Michael. Tries clearing all history and cookies as well, also tried in an Incognito Window.
Using IE or the latest version of Edge the users can see the form. Just not in Chrome ... and again not all users are seeing this issue.
We are currently using Enterprise 10.7.1, will be upgrading to 10.8.1 in the next few weeks, hopefully that will resolve this?
