Why did the audio on the web page stop working on tablet devices?

Question

iPhone

There is a site:

who needs the details

showroom-radio.com
Там по центру картинка клик по ней запускает аудио. Аудио сделано через
<audio>
есть js который получайте json, пример: user.radioboss.fm:2199/rpc/akuzne00/streaminfo.get
берет src для <audio> и player.play();
все просто, примитивно и работало везде до недавно

Everything is extremely simple and everything worked until recently. No changes were made. To date, infa has been received that playback, silence and that's all stopped working on iPhones.
Hence a few questions:
could you check this on your iphone as well?
what was updated, who knows? Mb blocks ajax requests, can audio files be the enemy of iphone now?

For religious reasons, I don’t have this wonderful device created by the gods, like a new wonder of the world, so I can’t debug. If you have any thoughts - in the studio, I will say thank you.
