This may not be the best place to post, but I'm having trouble with MobileMiner.  I have two RPIs each with ten 5-chip gridseeds.  I set up a MM account and set it up on one RPI.  I logged into the app and it showed up right away.  I set up the 2nd RPI the same way, except gave it a different name.  However, it won't show up in the app.  I power cycled the whole system (RPI, hub, PSU, etc) and still nothing.  I thought maybe it would take a while for it to register, but it has been over 14 hours since the power cycle and still nothing.
