Really struggling playing against people WITHOUT adapters

I've been floating in the 2400s for like 6 months and realized I'm having this issue where I'm playing it seems about 30% people without adapters and 70% people with adapters. I play well against people with adapters but the people without adapters they have those absolutely crazy sidespin shots that my brain can't even process because it's so different from real TT. We'll be in the middle of a rally, they are hovering over the table and jab awkwardly at the ball, and suddenly it's shooting away to the side.

I feel honestly really stuck. I'm also a lefty and I just get absolutely burned to my backhand side against non-adapter people because that's the way the angle is tilted.

Any thoughts/ideas?
