STORE_ERROR_UNLICENSED
The product does not have a valid Store license
STORE_ERROR_UNLICENSED means the Store licensing layer could not confirm an entitlement for the product or add-on. The failure should be handled as a licensing state, not as a generic network error.
Checks
- Confirm the correct Microsoft account and Store identity are in use.
- Refresh license information through the supported Store API.
- Verify package identity, product identifiers, and test-flight configuration.
- Check date, time, connectivity, and Store service status.
Application behavior
Protect licensed functionality without destroying user data. Explain how to sign in, restore a purchase, or acquire the required product, and avoid repeated purchase prompts while a refresh is still pending.
Offline and cached licenses
Follow the Store API's rules for cached entitlement and offline use rather than inventing a grace period. A temporary inability to refresh is different from an authoritative unlicensed result.
Support evidence
Capture product and SKU identifiers, package identity, Store account state, refresh timestamp, and sanitized correlation IDs. Never log purchase tokens or account credentials.
