Paul, I'm sorry, I don't understand your response.
Q.)--Did you not read my article linked above? (and below on this post which mentioned the top 4 browsers that NOW support autoplay, Chrome, IOS, Opera, & Firefox)
Q.)--Did you click the linked example for a demo (did it not autoplay for you )?
Q.)--Can you point me to your source which states something about this Software-Lock concerning autoplay?
-These are all real questions that I would like answered. I just find it hard to believe that you or anyone else on your team have never visited a website with autoplay on a mobile device.
-Concerning the fallback, yes, an image fallback would be nice, attached is an example from another pagebuilder I will not name, but I know of this functionality on at least 6 more popular page builders.
