Hi there,

We have a multi-tier concept similar to this:

Tier 1 - access to 1 course only
Tier 2 - access to 2 courses only
Tier 3 - all access to courses

And each tier will have 1 month, 6 month and 12 month variations.
Users can have only 1 subscription at the same time, and for example user can go from "Tier 1, 1 month" to "Tier 3, 6 months" subscription. 

So we have set up App Store Connect with the following:
- Only 1 subscription and all 9 variations created under the same subscription

But what about Google Play Console? Should I create one subscription and create 9 base? Or 3 different subscriptions with each of them having 3 variations (1 month, 6 months and 12 months)?

Also, should I create 3 entitlements or 1 entitlement in RevenueCat?
