Did you look under and if so, did everything look right?
I couldn't watch the video, for some reason.
You're going to want to start looking around this:
That grease is from the zerk, under the floorboard. You can see this same piece, in 4shorts video. He addressed the nut that helped fix the problem for rearward, but didn't show any nut for problems with forward motion. This cam, alone, was what made mine work right, when I bought it, a few months ago. The dealer adjusted this to my satisfaction, before I agreed to take it. If yours got moved all the way to the bottom (that's how mine was, when it rolled excessively), it's an easy fix you could try and return back, without issue, if that didn't isn't the problem.
I would be concerned the dealer would mess up something else, trying to get things back correct.
If you can take some pictures, someone here may be able to point out the issue.
I just went out and looked, it doesn't appear there is any linkage ahead of the part I pictured. It looks like it all goes rearward, toward he transmission, which makes sense.
