Safari on iOS has strict autoplay policies for videos, especially background videos. The behavior you’re experiencing may be due to updates in iOS or Safari’s policies, which limit autoplay to reduce data usage and avoid unexpected audio playback.

There are some workarounds that might help. Try a JavaScript fallback to trigger play programmatically.

However, if the device is in Low Power Mode, Safari may block autoplay entirely, regardless of settings. Unfortunately, there’s no direct workaround for Low Power Mode limitations on iOS, so users may need to tap play manually.
