ChatGPT is great but this app is not. Two major frustrations, firstly: the slightest right swipe in the app makes the chat disappear and brings up a menu. If I wanted to get into that menu, then I would tap the menu icon in the upper left. It's very frustrating. Second frustration: if I ask a question and ChatGPT is typing an answer, if I switch to another app in that moment and then come back, the last question and answer will have both disappeared from the chat.
