I'm quite sure it worked in the past.
I don't have Chrome installed on my Android. Only on my laptop. Connecting by USB my Android with laptop with Chrome is my current workaround...
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.
Thats odd - you're sure it worked in the past for you with the App Loader in Gadgetbridge?
If you disconnect Gadgetbridge, then go to https://banglejs.com/apps/ in Chrome and connect that way, does it all work ok?
