Description

By the current design, once a dt is generated it needs to sync to other routers as well as backing up in the state store, therefore there is a time gap between other routers are able to know the existence of this token.

Ideally, the same client should be able to renew the token it just created through fetchdt even though two calls are hitting two distinct routers.
