No BBC Radio 3 on Apple Music Radio

In June 2021 BBC Radio 3 stopped working in the Music app on my iPad and iPhone.

It was still working fine on my Apple TV 3, and in iTunes on MacBook Pro and Mac Mini (Mojave).

All other BBC Radio stations (1,2,4,5,6) continued to work in the Music app.

I tried on different WiFi networks, and other peoples devices. Not working.

On 16 June I contacted TuneIn which “supplies” the feed.

By 30 July it still wasn’t fixed and I contacted them again.

They replied “We have already reached out to BBC and is actively working on a fix regarding this issue.

Thank you for your patience.”

It’s now 4 October and it’s still not working.

Luckily it works and has always worked in MyTuner.

But why not where it has always previously worked in Apple’s Music?
