I’m using the latest Screenly OSE from master (f2cbd9f) and I don’t see the functionality referred to in this post about adding headers to assets: https://support.screenly.io/hc/en-us/articles/360011642714-How-to-use-Screenly-with-Grafana
I don’t see an “Advanced” option when adding an asset. Is this only in the pro version? Is it available in the experimental OSE version?
