I setup the Deco Mesh. It WORKS but I need to change a password on one of the devices. I connect to the Wifi for that device but the app says it cant find any devices. 

I can connect via browser to the UP and see the status of everything. I can see the device for which I need to change the password via browser, conneect clients, etc.., AND I can see the password. In the app it did show the devices but then after a firmware update it onlly shows the main device. I can still connect to wifi/internet via the device in question but it doesn't show up in the app. Is there any way to change the password for that one device on the web interface?
