Environment:

• iOS app using the latest RevenueCat SDK

• Subscriptions set up in a single Subscription Group in App Store Connect

• Monthly subscription (Level 2) and Annual subscription (Level 1)

• In Sandbox 

Steps to Reproduce:

1. User purchases the Monthly subscription.

2. Before the Monthly period expires, the user purchases the Annual subscription.

3. RevenueCat webhooks are received in this order:

   • PRODUCT_CHANGE

   • RENEWAL

   • CANCELLATION (with product_id corresponding to the Annual subscription)

Observed Behavior:

• After upgrading, the CANCELLATION webhook references the Annual subscription, causing our backend logic to treat it as if the new subscription itself was canceled.

• When the Annual subscription naturally reaches its expiration date, it does not auto-renew, confirming that the annual plan’s renewal has indeed been disabled.

Expected Behavior:

• CANCELLATION should reference the Monthly product (old plan).
• Annual subscription should continue auto-renewing at each billing cycle.

Questions:

1. Is it expected that an upgrade flow emits CANCELLATION for the new subscription’s product_id, or is this a misconfiguration?
