Make sure the Deco is not running in access point mode (Advanced > Operating Mode). In AP Mode, there are fewer options compared to router mode.

If you set up the Deco with your email, then you should be the owner, and not a manager already so that should be fine.

I would also reboot the system if that has not been done yet.

@Tony when I open the advanced setting nothing comes up. It's a blank. I'll try rebooting the system by disconnecting all the powers source and maybe even reconfigure the network. 

@Gizmokr 

I have the same problem. The app shows nothing. No Deco's, nothing connected and virtually no options.

I posted this in Deco forum but it got deleted 🤔

@Gizmokr I am seeing a blank Advanced section in the Deco App on Android as well.  

@opendave 

have you tried power cycling main deco?

@mjrw85 Yes, a couple of times.  And verified I am running the latest firmware too.

@opendave 

I was able to fix the problem only by deleting the network and set up as a new one. Power cycling and resetting wouldn't just do it. 

@Gizmokr that sounds like a major pain.  Are there any new features worth the hassle?  For example, has the ability to specify WiFi channels finally been added?

@Gizmokr 

I'm having the same issue. Not settings possible in the app. The wifi seems to be working bit I need to makensome changes to 2.4 network but can't do it. Was there any solition in the end?
