I'm not quite sure what the "long link" function is/was, how it worked, or if I ever used it.
I know when posting from my tablet, I have difficulty embedding here due to a different code that accompanies the videos - it usually starts with an "m."
Is that the long link?
Anyway, the only way it works for me is to use my laptop, accessing Internet Explorer.
I'm not sure if that is the answer you were looking for. You can always post a question on the Comments Board. Ron answers in many threads there, and he's also got a tech-support guy who sometimes chimes in on these types of matters.
