I have been researching for a few days and haven't found a conclusive answer to my scenario.

I would like to provide two subscription types on iOS:
```
Lite
```
and
```
Standard
```
.
I would like to provide one subscription type on Mac:
```
Standard
```
.

Standard is the bigger service that covers both iOS and Mac. Lite is the lesser one that only supports iOS.

Based on what I see on AppStoreConnect, Mac has a complete separate IAP than iOS. Hence I can't share the same

standard

subscription type among the two platforms. Even though the

standard

service is supposed to be cross-platform.

I can certainly store each receipt type from iOS and Mac into my DB separately and do the validations directly with AppStore and MacStore respectively. But I can't stop the user from purchasing the

standard

subscription twice, once from iOS and then again from Mac. This is really bad since I wouldn't be able to refund it either if someone makes this mistake since Apple regards them as two different apps.

Surely I can't be the only person with this problem, how is that supposed to be done, please?

"But I can't stop" Yes you can. Before the user in iOS or Mac can purchase the subscription you require that they log onto your DB. If your DB indicates they have a subscription on their other system (i.e. Mac or iOS), don't let them make the purchase.
