I did some research and tested this site I made [www.nederlandsecontentproducenten.nl] (http://www.nederlandsecontentproducenten.nl/) in Safari iOS 13 & iOS 12.
In iOS 12 it worked fine, in iOS 13 a play button appears… Does anyone know why it isn’t working in iOS 13 anymore?
Solved: I don’t know why but the next morning the video plays in iOS13.
