iOS web browser latency issue

[Emefar]

We creating a broadcast with an iOS or Android native device. We have a interesting problem with the delay in the broadcast.

Here is some delay times for different variants.

Android Native -> 1 second latency
iOS Native -> 1 second latency
Web -> 1 second latency

Web on Android device (Chrome) -> 1 second latency
_Web on iOS device (Chrome) -> 18 seconds latency
Web on iOS device (Safari) -> 18 seconds latency

We cannot watch streams on ios device on web. We are watcing streams perfectly on Android device (on Android's chrome web browser) but we cannot watch on iOS (on Safari or Chrome) device.
