I was playing on an indoor court, where the net is fixed on portable trolley, with a tube in the middle and two L-shape stands on each side, like the one used at the Sampras/Fed match. My opponent plays a drop shot just clear the net and bounce on the tube first. I rundown the shot and hit the ball after it bounce again on the ground. My opponent stops and said the ball bounce twice. I said the tube is part of the net not part of the ground, so it counted as ‘let-during-play’, and I can let it bounce once before I hit Who’s right?
