Chat features - send messages to every client logged doesn't work

Hello all,

Server: Openfire 3.7.1

I enabled this features:

route.all-resources - Enable routing of messages to base JID to    every client logged in with the same base JID (different resources)    and the same (highest) priority

When I am logged in from my PC and phone and session are both with the same priority(1) messages are not send to both devices, only to one.

So, I suppose this features doesn't work at all.

Any feedback and instruction are accepted.

Thank you in advance.
