>>4287902There’s a chance that your tripod actually doesn’t have a reversible screw and you actually need to attach a head or a plate, as you mentioned. Don’t force it if it won’t come out lol. Some of the more expensive tripods and video tripods are like this, head sold separately. You’ll need to buy something like picrel. See
