Out of nowhere starting today (10/13/29) whenever I log into my router or refresh the page I am getting a "New feature available" popup going off about AiMesh.
The popup is controlled by an nvram flag - if it reappears, then it means something is preventing the "already seen" flag from being set in nvram. Make sure your nvram isn't full.
It usually happens to me if I have stale login credentials.
Check the traffic analyzer page. If that fails to render properly, then its likely the same thing I get. Manually log out with the logout button, then log back in.
