Why are you putting the potty away? just leave it sitting out and see if she asks to use it, or sit on it. most experts say to reward (praise) them for sitting on it not for being successful. Do not expect her to completely empty her bladder or to make it there in time. She's not probably not emptying her bladder all the way because this is stressful and new. I put the potty our when my son was about that age but I had NO expectations for being completely potty trained until three. It's just out for occasional use, no pressure. As in ALL things we should praise EFFORT not success. If math is easy for a child but reading is hard it doesn't mean she deserves more praise for math she may be putting zero effort into performing in math class and working very hard in reading. If she sits on it while wearing a diaper smile and say "wow you look comfortable, you must be getting big!"
