Help! Getting very few TOS impressions but tons of product page impressions. Here’s what I’ve done…

I just launched a new product and my PPC strategy is failing.
I have high volume, relevant KWs in their own campaigns exact match with bids higher than the suggested range. I have low volume, relevant KWs at a quantity of up to 20 per exact match campaign, also higher than suggested range.
For almost all of the high volume KWs, my TOS IS is almost non-existent; but when my product shows, it has a high CTR and sales. For those same KWs, Product Pages impressions are 1000s of times higher than my TOS IS.
What I’ve tried: I was doing dynamic bids down, changed this to fixed — helped get impressions (wasn’t getting any); then, I increased the bid adjustment to 900% and changed the bid to 1/9th of what I had (higher than top of the range) — this led to no change.
Not sure what to change at this point. My previous product felt a lot smoother, I immediately dominated in the KWs and I used the same starting strategy (but that was earlier this year). Anyone else deal with this?
