Viewing older chats had become a nightmare

Hi! It’s been a month since you responded to me. Sorry for the delayed response, but I had been scared to update my ChatGPT app. Because, if I were to update the app, and it so happens that the newest version of ChatGPT not only didn’t solve these problems but also introduced new bugs which made things even worse… then I would be in regret. Once I update the app, I can’t down-date it back. So, I need to confirm that these bugs are no longer present on the newest version of the app, and that no other bugs are affecting the ability to view older chats, before I can feel safe updating the app.
