Video not playing on WebGL when using low power mode on iPhone or iPad

Information
Unity 2021.2.12f1
iPhone 12 Pro (15.0)
iPad 8 (15.3.1)

If I turn off low power mode on iPhone or iPad, A video can playing on WebGL using Safari and Chrome. But If I turn on low power mode, THE VIDEO IS NOT PLAYING.

This is the error it is getting.

Invoking error handler due to
NotAllowedError: The request is not allowed by the user agent or the platform in the current context, possibly because the user denied permission.
play@[native code]

By the way, when I using babylon.js, the video can play on both mode when I switch on and off the low power

Who can help me solve this problem or have any ideas or suggestions?

same here

Same. Video was working moments earlier, then suddenly it didn’t.
Then futile moments of debugging, only to find out it was low power mode!

do you see any errors in the browser console besides:
The request is not allowed by the user agent or the platform in the current context, possibly because the user denied permission.
