I'm testing the purchase of a product with a trial offer using the newly created sandbox account in my app. However, when I check the user profile, I see that the state is "Auto-renew off" as soon as trial starts. After the trial converts, the state updates to "subscribed". In store purchases, the state is "Active trial" after trial purchase. This is the correct flow start for user's state. I don't understand why sandbox purchase act like I mentioned.
