# Sandbox Free Trial Isn’t Appearing

Why free trials sometimes don’t show up in sandbox testing and what to do about it.

This can happen when you've previously purchased a subscription and then reinstall the app during sandbox testing. The issue:

* The on-device receipt is used to determine trial availability.
* In sandbox, this receipt isn’t retrieved until after a purchase or restore.
* So the SDK can’t determine if a free trial is available at app start.

**Fix:**
Restore purchases first, then try again. This won’t happen in production.
