Having the same issue - been waiting a couple of days for support to come back to me. It's strange because I have two sites. The 7.1 it works perfectly well on chrome with video banner - the 7.0 is not working. The other issue is that instead on popping up with the fall back image it just shows a black background to all my widgets. Any ideas on how to fix this yet? Has anyone heard anything from Squarespace on expected fix time
