I have two PAP2s that lost registration and I couldn't get them back up. I live chatted with tech support, and they couldn't see any problems on their end. Both were previously set up to connect to west node, so I switched one of them to central, and that one came back up. The other PAP2 that was still on west continued to bounce on and offline, so I swicthed that to central too, and it now also seems stable. I'm just wondering if anyone else is having problems, since tech support didn't see any problems on their end.
