Nighthawk 6900 device manager not showing connected devoces

[Citydweller11]

Hello for the last six months my Netgear nighthawk are R6900 device manager has not been showing all connected devices. This used to work really well where you could see everyone connected to your Internet and control the connection of those devices. Currently using firmware V 1.0.2.26. I have tried everything short of completely resetting the router which I do not wanna do. Any suggestions on how to get this back? Using iOS 15.5 and app version 2.18.0.180.

do they show up in the access control page? 

I've seen a lot of issues with the attached devices page. Sometimes a reset fixes it, sometimes you need to downgrade if it bothers you

They do show up on access control page for the most part. What do you mean by downgrade?

You can try downgrading the firmware a version or 2. I've seen updates to firmware cause issues with the attached devices list. Or you can just use the access control list.
