CVS Beginner question: (when) do extrabucks rewards break rebate apps?

Hello again to my worldly and scholarly comrades, wise in the ways of CVS. I find myself once again in need of your counsel.

On popular rebate apps like ibotta, I believe that many offers will fail if they are combined with other coupons, particularly manufacturer coupons.

1. For rebate app offers like this, do extrabucks offers tend to mess up the rebate offers? I'm talking about offers like "get x extrabucks when you spend y on z category."
2. What about redeeming extrabucks when making a purchase? Does that look like using a coupon to apps like ibotta?
