I also just tried it on Android Firefox v118.1.0 and Android Chrome 117.0.5938.61 and got the same result

Looks like it's working, thank you. This was driving me crazy thinking I had my project hooked up wrong

Thanks for checking! Most of the times, the opposite is actually true - users miss something and they blame the simulator. But in your case it was actually a simulator bug. While at it, I noticed that we also don't respect the UART baud rate setting for the RP2040, so a fix to that is also on the way.
