Creating a link that automatically plays the song for iPhone

Hi guys,

I wanted to create a link to an AM song that, if you click it, plays that song automatically. This is obviously not the case for usual links, as they only open the album and highlight the linked song.
However, I figured out that if you add &autoplay=true at the end of the URL, it plays the song upon clicking the link.

Sadly, this only works on my iPad and not my iPhone... does anyone have an idea why that may be?

For reference: my iPad is quite old and still running on iPadOS 16.7.10. I dont know if that has anything to do with it...?
