Can customer subscribe to the same subscription if they are already subscribed (opted-out but not expired yet)?

Thanks for the detailed write-up and screenshots!

So, when a customer cancels (opts out of renewal), they don't lose access immediately, they keep their subscription until the end of the paid period and if they resubscribe before that period ends, Google Play allows it and backdates the new subscription to the original renewal date.

That's seems to be why you see a new subscription start and the old one expire at almost the same minute, where Google is aligning the billing cycle.

For this flow, RevenueCat sends specific webhook events:

• CANCELLATION: the customer opted out of renewal, but still has access
• UNCANCELLATION: the customer re-enabled auto-renew before expiration (they never lost access)
• EXPIRATION: access is actually revoked
• RENEWAL: a new billing cycle started. Note that Google Play may classify a resubscription as a RENEWAL rather than an INITIAL_PURCHASE

If your backend is treating CANCELLATION as "revoke premium," that's likely where the sync issue is coming from. You'd want to keep access active on cancellation and only revoke on EXPIRATION.

Some extra context on this:

• Common Webhook Flows walks through cancellation, uncancellation, and resubscribe sequences
• Event Types & Fields has the full reference for each event
• Google Play subscription lifecycle on Android's docs also explains the cancel/restore behavior from Google's side

Let me know if you have any questions! Feel free to share the affected App User Ids too, to try and investigate/confirm the Events on the Customer Profile.

Best,

Thank you ​@guilherme for the reply.

I’ve looked at the webhook events and there is no `UNCANCELLATION` event triggered. Also, I only revoke premium access on `EXPIRATION`.

If you look at the second image I shared, The subscription started on `2026-03-07` but user manages to resubscribe again on `2026-03-23` and the expiration happened shortly after that. The monthly subscription cycle was not completed yet.

Where can I share the App User Ids? Is sharing here safe? Also do you need the project ID?

Thanks
