@PlastiBots, I use tp-link Deco app. This is the app recommended while installing the Router!

@ImEasy Hope these screenshots help you... I am using IOS, this is the only app I use , version 3.6.50;

I found a workaround from phone app to remove a registered device - * Click on Online clients * At the bottom, click on Offline Clients * Use option Clear All on top right if all offline clients...
