## **Description**
app is using revoked tokens to refresh token.
That should not be the case, as we only revoke token after successful
renew refresh token.
We are speculating that user might closed the app before the redux state
are persisted on the files

This PR add a delay of 15 seconds after successful renew refresh token
before call revoke token
