Ionic in-app purchase multiple app accounts

#1

Hi, I’ve a question about in-app purchase subscription. In my app you can create multiple account.
this is an example of my problem.

Login paolo.rossi@gmail.com and buy premium,
Logout paolo.rossi@gmail.com
Login paolo.verdi@gmail.com
I’ve already premium and I can’t buy
How to solve this?
In many app you can buy premium in the same phone with different account. is it a ionic limitation?
