HomePod not playing music purchased in iTunes

Since iOS 18.2 came out in January I have been unable to play my purchased iTunes music on my HomePods by asking Siri to play album xxx or song xxx. I don not have an Apple Music subscription. She always responds with "sorry there was a problem with Apple Music" or "sorry I an unable to find artist/song in Apple Music". She will however play all music, and then when a track is playing you can ask her what it is fine, but then if you ask her to play the very track she is playing she will respond with one of the errors above, even though she is playing that very song!!

I've tried everything with Apple Support to remove devices, re-add, send logs etc... We've been through iOS 18.3, 18.4 and 18.5. I've even installed iOS 26 on one HomePod to test, but all still have the same error!!

I surely can't be the only customer that's been experiencing this??? And a 6 month outage is pretty poor!!

I've had 2 tickets open with Apple Support since February 102525****** and 102643******
