I'm having some issues with iOS 15.0.2 version. I added video to my website as a background. So I put it style with fixed position via CSS. But it doesn't showing on iPhone with iOS 15.0.2 version. It's working well on other devices and iPhone with other version except 15.0.2. I tried adding fixed position via JavaScript but it still doesn't work. Whenever I changed position to other values like static or relative, the video was playing well. I can't find any solutions to fix it.
