UserB is offline. UserA add and request presence subscription to UserB. When UserB logged in, The callback on_incoming_subscription is not called. <- the problem If UserA will send another request while UserB is online, the callback is called. Sorry for the late reply. I thought this requires some coding to reproduce it, but turns out perhaps this is just a misunderstanding. The on_incoming_subscribe() is only called when incoming SUBSCRIBE is received (as the name suggest!). So in your cause above, even if UserB logs in, the callback will not be called if UserB does not send SUBSCRIBE to UserA.
