As a counter I've found that the iOS app is insanely unreliable. I've lost chats, it messes up and says there has been no response, connection lost and more. It's been really bad. Often when it's reported no result and failed, I go to the site and everything is fine. If things fail I no longer retry as that's how I've permanently lost history before (which is insane, don't lose my shit), and go and check the website.

Insane ratio of "app quality" to "magic technology". The models are wild (as someone in the AI mix for the last 20 years or so) and the mobile app and codex integrations are hot garbage.
