Music stops playing during the night since new update - Music and spotify

I play music throughout the night (every night) and have noticed since I did the new update last week music has been stopping throughout the night - I’m unsure of the timing but I’ve turned it on again throughout the night (after waking to eerie silence) and it’s stopped again by morning.

My husband’s phone plays music too (Apple Music) in our eldest sons room and it’s also stopped by morning - so that rules out it being a Spotify issue.

Anyone else notice this and figure out a fix?!? Surely I’m not the only person who listens to music throughout the night!
