Little orange notification icon, little orange message where the input select drop-down would be. Next up, we would recommend that you also restart the device you are trying to sync up. As soon as that is done, you can now hit restart on the Hue Sync app.
At least, turn off the smart lights in the room you are currently in. Well, I tell a lie, it does find the bridge and when I press the button it momentarily says it's all good and then immediately loses connection again. The first thing you will need to do is ensure that all the lights are off before restarting. It's been flawless for ~6 months now and after a router reboot a few days ago can't find the bridge. I'm having a similar (the same?) issue with my sync box. The whole setup is currently an extremely expensive HDMI switch, having replaced one that cost £15. If there's a different factory reset method you used I'd love to hear it. It feels very much like coincidence though, given when I set this up first time around it was my standard router setup. Naturally I tried turning 5GHz off again and got scenario 1 again and again 'til I gave up, very frustrated. I finally turned 5GHz back on to use with other devices and on a whim tried it after a couple of hours. I've read a bunch about WiFi network bands impacting the process, so disabled my 5GHz band for a couple of hours whilst I tried to connect. It connected fine but took me back to square 1. and no matter how long I left it held in after the green flash the unit would just go into standby (red light) mode and the app wouldn't find it. I got to the point you need to hold the power button 'til it flashes green then let go. When you say you factory reset it, do you mean you deleted it in the app then held the power button for ~15 seconds until it flashed blue? I've done that today 'til I was blue in the face (no pun intended) and subsequently gave up. Well, I tell a lie, it does find the bridge and when I press the button it momentarily says it's all good and then immediately loses connection again. So a direct connection provides the best.
