Check Subscription with trial be used before IAPP-4.5.1

Hello Everyone! Please tell me, How can I find out if the user has ever bought a subscription on an account in the Google Play application? I can not determine if the user has spent the trial period or not. I used Unity 2021.3.6f1 and IAPP-4.5.1. Thanks in advance for your answers!

Hello,
Unfortunately, Google Play doesn’t return that information so there’s no way to directly determine if the user has spent the trial period or not.

If you have your own backend, one option would be to keep track of which subscriptions are in the trial period:
SubscriptionInfo.isFreeTrial()

The user can also verify in the app by opening the purchase UI. If the trial option is available, it hasn’t been used.
