Weird. That doesn't happen to me on iOS - I can post the question, wait just long enough for it to display "Thinking...." and then go and do something else.

It even shows me a push notification at the top of my screen when the search task has finished.

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.
