Can’t subscribe to premium on more than one account (mobile)

So today I bought a $15 apple gift card to buy premium, I successfully was able to purchase premium on one account, but when I wanted to buy it on my second account, it wouldn’t let me. It could be because I already have the subscription one on account but I should be able to purchase premium on multiple. I have a screenshot here of the error message:


If you use the same Apple account, I think you will not be able to buy Premium on other account. That’s because Apple probably detects that it’s active.
(I suppose that you are using some Apple service)

Wel is there any way I’m able to get premium on the second account ?

Probably if you got a bigger tier… Like, Premium 1000

There’s only the 450 premium option not $10 or $20

I have no idea why. Try subscribing in the desktop website perhaps?
