This last June we were directed to a precheck line in MIA which was very fast after immigration.
That's a new development. Our last connection thru Miami was in December, and we were given a yellow card to show to the screener. We assumed that meant that the usual Pre Check rules applied with that card, but when we arrived at the line we were chastised because we didn't remove our shoes and take our liquids out. When I stated that we were Pre Check, I was told I should have read the card. Sure enough, it said we had to do those things.
