Doesn't receive (onMessage callback) retained Message after subscription

I am trying to handle short mqtt connections between long (60s) deep sleep sessions.
Sequence:
Start
WiFi connect, wait connected
Mqtt set callbacks
Mqtt connect, wait connected
Get variables from ulp and publish
Disconnect mqtt & wifi
Start Deep Sleep
Before mqtt connect I subscribe to an update-request. After connection I would like to handle incoming retained topic, but never receive anything.
Anyone getting retained Message working?

You can only subscribe/publish/unsubscribe when connected.
