You know, I tried the online lessons path. Worked with a guy in london, I'm based in Pakistan and there are no certified / trained coaches here.
The guy told me I needed wrist hinge. I tried that for months and only managed to move the wrist a few inches by the time the club reached parallel on the backswing.
As a former student for 2+ yrs I don’t think this is true. His concept is simple, be still and closed through impact while having a single swing thought. Do you have a video where he talks or teaches this advanced version?
You need continued lessons with a pro, whether online or in-person. Comments on a forum like this one can point you in the right direction, but ultimately, you need a pro to work with you for best results.
