Okay, let's slow down for a second, because I can feel the frustration in this post. That banned ad? That's the best lead you've got right now, and you're moving past it too fast.
You had 10 sales for about $273 spend. That's a $27 cost per sale. Whatever that creative was saying, it was working. Then version 2 gets 3 sales on a similar spend, and your brain is screaming "version 2 is worse!" Maybe. But it could also be random noise, the account taking a hit after the ban, or you accidentally cutting the exact line that was doing the heavy lifting when you cleaned it up. Three sales versus ten at that spend level... that's not enough data to know for sure what happened.
On the ban itself: scar treatment lives in the health and personal attributes category. The flag is almost certainly before-and-after imagery or copy that implies a physical change in the person reading it. this isn't a vague policy, it's a very specific one. It's worth reading those two sections properly instead of guessing which piece to cut. Most people in this niche get banned over and over for the exact same core reason while thinking each strike is a new problem.
that advertorial with a 7% click-through rate that didn't convert? that's not a bad page, that's a mismatch. a 7% CTR is high. people clicked because the ad promised something the page didn't deliver. Read the ad and the first paragraph of that advertorial back to back, out loud. Usually, it's two completely different conversations.
Now, on your actual question. you can't diagnose anything at $1700 spread across that many changes. You've switched creative source, format, angle, and funnel type. There's no control variable anywhere, so none of your learning so far is reliable. That's the real bottleneck, not the specific creative.
here's what I'd do first. Take the angle from that banned winner, build one compliant version, and run it against one variable at a time. Same audience, same page, same daily budget. Change only the hook. Four ads that differ in just one way will teach you more than forty ads that differ in ten.
Static versus video is a fair question, but it's not your bottleneck. You'll be able to answer it in a week once you have a control to test against.
