I never saw that bug, I don't think, but there was one where it had to start the response before you switched away. That's thankfully been fixed for a few weeks.

That has never happened to me. Did you try that a long while ago? I only had that issue with Gemini

Don't worry, the Gemini website does the same, at least on Firefox mobile. You switch apps and you lose the response AND the prompt.

Normally some software devs should be fired for that.
