Hello IHeart8008s,
We would like to see how we can help you with Spotify not playing as expected. Do you have any updates avaiable for Spotify? Do you have any updates avaiable for the WatchOS or iOS? If not, you will want to reach out to Spotify directly to see what might be causing this issue with the steps in this link: How to contact an app developer - Apple Support
"Contact the developer of an iOS, iPadOS, or watchOS app
- Open the App Store on your iPhone or iPad.
- Search for the app, then tap it. If you can't find it, tap the account button
or your photo at the top of the screen, tap Purchased, tap "Not on this [device]," then tap the app. - The app's product page appears. Scroll to the Ratings & Reviews section, then tap App Support. If you don't see App Support, make sure that you're signed in with the correct Apple ID."
Cheers!
