Safari / iOS 17.2.1: After audio end, changing audio src/source does not allow play

Apple iPhone SE

Version: iOS/Safari 17.2.1

This previously worked on iOS 17.1.2

As a user using safari on an iPhone

When I am listening to an audio chapter/file in safari

I want to be able to continue listening to the audio with safari running in the background (ie at the homescreen, locked or using another app)

When the audio/chapter reaches the end

I want to change the src to the next audio/chapter

And play automatically

On iOS/Safari 17.2.1 playing the next chapter does not allow play automatically

Actions:

* Open Safari

* Play audio player

* Open another app or go to home screen

* Audio still plays

* When audio ends

Expected:

* Next audio file is loaded

* Next audio file plays

Actual:

* Next audio file is loaded

* Next audio file does not play

Questions:

1. Is this an intentional update?

2. If not, is there a possible fix in iOS 17.3.0
