It is impossible to cancel a subscription cross-platform, i.e., you can't cancel a Google Play-subscribed Premium on an Apple device and vice versa.
You can unsubscribe any time.
Even though you cancel the subscription, you can enjoy its features to the end of the subscribed period.
If you don’t cancel it, the subscription renews automatically.
