The session’s presentment intent assertion timed out.

```
case presentmentIntentAssertionTimeout
```

## Discussion

A [`CredentialSession.PresentmentIntentAssertion`](/documentation/SecureElementCredential/CredentialSession/PresentmentIntentAssertion) granted by a credential session lasts for 60 seconds. If it expires, your app needs to request a new one with [`acquirePresentmentAssertion()`](/documentation/SecureElementCredential/CredentialSession/acquirePresentmentAssertion()).
