Hi Folks - I am attempting to set up a mobile push configuration, by following the published example(s).
If we have more than one endpoint registered, this configuration works as expected (via the ts_store() path below).
If we do not have another registered endpoint the transaction seems to be suspended but then cannot be resumed (t_suspend) after REGISTER arrives.
