Hello kelseyhawk7,
We are not sure if Spotify requires you to change your payment method on their website or something else, but we can definitely guide you on how to update your Apple payment method. If you are paying for your Spotify subscription through Apple, this should accomplish what you are trying to do. Please take a look here: If you need to change or update your Apple ID payment method - Apple Support. Follow these steps to update your payment method on your iPhone:
- "Open the Settings app.
- Tap your name.
- Tap Payment & Shipping. You might be asked to sign in with your Apple ID.
- Tap Add Payment Method, enter the new payment method, then tap Done.
- Tap Edit.
- Tap the red delete button next to the old payment method, then tap Delete."
Let us know if we can help with anything else at all or if this doesn't settle your issue so we can look into this further with you. Thanks and have a fabulous day!
