Subscription isn't recognised on a different device

I decided to subscribe again as the live notifications on iOS were a “must have” feature for me so I was glad to see they’re now available. But I subscribed on my Mac, and now when I login on my iPhone (both using “Sign in with Apple”), it doesn’t recognise that I already have a subscription. I just have the popup “Your trial period is over… Choose your subscription” and there’s no way to “restore purchases”.

(Also, on iPhone I re-downloaded the app and it made me go through the onboarding AGAIN - I think it should give the option to sign in before going through the onboarding process)
