@js-14 Nice to see you around the community.
It looks like your account is currently upgraded through Apple.
The option for an annual subscription to Pandora Plus, Premium or Premium Family is only available if you upgrade directly through Pandora. Apple only offers monthly subscription options when upgrading from iOS devices.
To switch to a yearly subscription, you will need to cancel the subscription through Apple, and wait for it to expire. Once you begin to hear ads, you can then upgrade to the yearly service offered on the Pandora website.
Unfortunately, I can't manage this for you, as I don't have access to the Apple billing system. You can check out Apple's cancellation steps for more info on how to manage your subscription from your preferred device.
Once you start to hear ads again, you can resubscribe directly through the Pandora website at the annual rate. Please note that once you've upgraded, your auto-renewal option and payment information can only be managed from the subscription details page. Let me know if you'd like those steps.
Hope this helps.
