S2S presence not working between wildfire 3.0.1 and 3.1.0

I have:

Wildfire 3.0.1 setup with LDAP auth and local groups, embeded DB. I also have auto allow for subscriptions and presence

Wildfire 3.1.0 beta setup with LDAP auth and local groups, embeded DB. I also have auto allow for subscriptions and presence

I add a user from the beta server to the 3.0.1 server via published groups. Users can see this user only as offline, and not their true status…

Any other info you need please let me know
