I just bought deco x20 few days ago and set it up as a main deco to replace deco m5. It works fine like my old ssid and password still there, internet works ok but on deco app, the wifi settings part disappeared and I can't even turn on guest wifi. I tried rebooting, reinstalling app but nothing works. I don't want to go full hard reset because it's annoying when it comes to pppoe account.
