Great the video is now working but still the html still just shows the red lightening symbol only, with no input or output.
With that aside I am not making any headway with responsive columns.I can when I use your templates but they don’t do what I need, I would like to create a video wall of 50 + videos of 6 thumbnails with titles beneath each, to each row, reducing in sequence to just 2 per row for mobile. I have tried to emulate the templates to no avail How do I achieve this please from scratch. I can get the videos playing through one Lightbox that spans the full width of the mobile but getting the columns to break correctly escapes me.
