Apple Music in airplane mode works on my Samsung phone but not IPad Pro?

Hello

i need a real answer to this annoying problem. When I am on a plane in airplane mode but try to play DOWNLOADED songs the Music app cannot play the files unless I drag to around half way through the song.

but Apple Music on my Samsung phone in airplane mode works PERFECTLY FINE.

weird thing is last week on a flight to Mexico it played fine on IPad. But on all other flights this year it has been an issue.

What is wrong with my Apple Music on IPad Pro? My IOS is updated, Music app is updated, and music is downloaded properly.

best
