This is extremely frustrating. I have been using the P9 for a few weeks, during which time the device list showed everything on my network. Over the weekend, I installed the app on my wife's phone, but the device list would not populate. Later, I tried adding/removing devices from my kids' profiles, but the changes would not save. I eventually tried uninstalling the app on my phone and reinstalling it. Now, I have no devices in the list on my phone either. I have installed the app on two other phones, both with the same results. For whatever reason, I cannot see or manage any devices on my network. I can still connect to the internet, but I cannot use any of the advanced features of the router.
