Is it possible to change this behaviour on the mobile site? Because with the main Android keyboards, you can't mimic the Shift + Enter behaviour. In other words, it'll send as soon as you touch the Enter key.
I was trying Assistant for the first time earlier and it took me a minute to realize why it kept sending my queries before I had done writing them. It was slightly frustrating 😶
For reference, on the ChatGPT mobile app, which I use almost daily, pressing Enter adds new lines; it doesn't submit the query directly.
