Does the trim work ?
Have you tried setting up the front derailleur from scratch ?
You can check if there is a fault of the shifter if you unhook the cable and hold it between your fingers and operate the shifter with the other hand. Does the cable move as it should when you shift through the clicks ?
It is the fault of the shifter. when I am moving the lever in the video the cable is not moving. It still has appropriate tension. And as I mentioned it will work out of the blue. After I stopped the video it actually moved the lever and it grabbed the cable and I was able to spin the pedals and shift. Then I shifted down into the small ring again and it wouldn't shift again. If I had a way to hold the camera and do all of that at the same time I would have.
What I am unsure of is if there is anything user serviceable within the shifter or just take it to the shop. It's only 6 months old so it should still be under warranty. I mostly don't want to have to run it down, drop it off, be without the bike until its fixed etc. That's largely why I got into doing my own bike maintenance decades ago.
