Another reason I'm not a fan of pavers on round pools. IMO ground pressure should be approximately the same between the legs and the bottom of the pool, so theoretically (IF YOU USE WATER PROOF GROUND CLOTH), the rate of sinking of the bottom should be similar to the rate of sinking of the legs, and even if it's say an inch off, as long as that amount is consistent all the way around and the ground is even and level, that should only affect the "cove" radius in the bottom corners.
Now that said, I think if you are installing a "real" AGP you should still use pavers according to the manual, and if you are installing a rectangular pool you should also use them--because they are going to want to move as the pool fills. My round pools, once I have a foot of water in them the legs are really done moving at that point. I drag em out as it fills once, and then tweak them slightly as it fills and then they're not moving any more.
Of course, now that you have pavers in place and sunk in, I'd probably leave them so as not to tear up the ground, I just hope you can recenter the pool to get everything lined up.
