Thanks, but that didn't fix it. "Debug Info" was already set to "Hide". I also had some other issues when connecting to the watch and loading apps, so I did a factory reset. Now everything looks good.
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
On your watch, under Settings -> Utils, set the "Debug Info" option to "Hide"
