How do I make a video to play on iOS mobile(safari iphone/ipad)?

Hi,

I tried to convert a video to mp4 H.264, mp4 H.265, mp 4 AV1, webm v9.

I tried to make the video setting autoplay /not autoplay.

The result is the same. Video is not playing on my iPad. iOS 17.6(latest).

Can someone show me a working sample? Many thanks

Another Later Edit:

Project exported with R190 works;

Project exported with R191 doesn't.

I will submit a bug issue
