Hello, This is a follow-up to my previous report. We have identified reliable steps to reproduce the issue. We have set up a test page with a standard tag. Since this problem occurs without any external libraries, so this problem seems to be with the native HLS player in iOS. Steps to Reproduce: Open the test page in Safari. Play the video, seek to a different position, and then pause it. Switch to another browser tab. (If the issue doesn't occur, switch back to the video tab, wait a few seconds, and then switch away again.) Environment: Device: iPhone 16 Pro. OS: iOS 18.5 Thank you for looking into this. We hope this issue will be addressed in an upcoming release. Best regards, Kazutoshi-Iso
