I had the same experience just last week. Her profile disappeared from the dating app. Fortunately, I had made screenshots so I’ll be able to recognize her again in the future. She had given me her phone number, so I made a couple of attempts to contact her by text message. She finally got back to me a couple days later. She was angry because I was not athletic enough for her. Fitness and athleticism never came into the conversation. Neither of our profiles mentioned it. In fact, her profile shows a comparatively frumpy person. My guess is this: She worked very hard to become very attractive, but didn’t update her profile for some reason. She may have mixed feelings about the situation. Nevertheless, her true attitudes came out in the end.
