Multiple subscription groups for experiments - risk of double subscription

Okay, a potential way to fix this would be to remove the paywall when the user has subscribed and let the user manage their subscription upgrade only from apple’s website/settings app by redirecting to the managementURL provided by the SDK. I think this is how it was intended to work, but now I cannot run experiments because I cannot target the app version for them, which means users that have not updated will run into this “double-subscription” issue 

Hey @Maxenceh,
 
You would need additional logic in your app to allow the user to upgrade, either by recording or knowing which subscription group they're in and showing them the corresponding offer or just send them to the device settings screen by using the managementURL as you described. I do think that's correct that this shouldn't be dependent on the app version. Instead you can inspect their purchases to see which subscription group they're part of.

Hi, is there a full example of this? I am confused about using 2 subscriptions group and potentially allow users to get this double subscription problem. Do i understand correctly that we are supposed to: 

1. Have 2 subscription groups, 2 offerings, 2 different prices
2. Have them accepted, A-B test
3. Find the winner, display one price (say price A) to 100% of users
4. Handle users already subscribed to plan B (from rev. cat users id?) by cancelling existing sub if they upgrade to another product (say monthly to yearly) 
4.1. Or stop showing paywall to subscribed users (at least for users subbed to plan B)

Am I missing something? 

We have also seen this behavior from a few users who wound up double subscribed and are not clear how to gracefully handle it.

It’s also possible that the user could manually change their subscription preference by going to the settings where they can see all the subscription groups they were previously subscribed to. They can then manually switch to the cheaper option! Since we’ve only stopped the experiment, we haven’t deactivated the specific subscription group.
