Attached Devices Not Showing

After searching the Discussions, I am assuming that the not showing Attached Devices issue has not been "solved" for all models and all firmwares.

Is that correct?

My R6700v2 is up-to-date according to the check for updates option.

I'm trying to trouble shoot an issue with IoT devices on my 2.4GHz network and need to see a list of devices to figure out which ones are on that network.

The Nighthawk app is hit or miss with Device Manager sometimes showing them and sometimes not.

Where is this problem located? In the firmware, hardware, software, web browser, ???
