So I had enabled IPV6 and then wondering why I couldn't see my client list in the Android app, so after I read the warning(smh) I decided to disable IPV6 and reboot the router and my phone.
Still can't see my client list in the app so:
I have rebooted the phone(and router), uninstalled the app and forgot and logged back in the WiFi all with the same issue.
I'm running the stable and latest version of the router firmware, my router is the Flint 2.
