I’m running a React app in Screenly. I found I had to build it with polyfills to get it to load at all. I’m encountering a further error calling an API.
Is it possible to access console output from the browser (Which I understand to be UZBL) to debug the problem?

I’m not sure to be honest, but I would probably recommend that you switch to the experimental branch to see if that solves the issue instead. Uzbl is pretty dated by now and i known to struggle with modern web.

How can I switch to the experimental branch? There doesn’t seem to be any docs to do this.

Run install.sh and choose experimental.
