Following this as well. Setting up a Hydro-force Steel Pro Max Frame Pool Set, 12-ft x 39.5-in from Canadian Tire and running into the same issue. We have 12x12 pavers for each leg, with the radius from centre at 5'9, so we should have 6" of leeway, but still can't get the legs to 90 degrees. About half the legs are bend inwards. The band is extremely tight, so as soon as we move on leg, it shifts others. Currently have the pool about half full to see if the band will stretch. Have also reached out to Bestway support. We'll see if they have any solutions.
