I recently bought Tenda Nova MW3 WiFi Mesh sysytem from PcByte.com. All the deveices connected to the mesh without any trouble.
But my Lenova Smart Display adn JBL Link View increasingly says "Umm Something went wrong, Please try again later" or "There seems to be glitch, try few minutes later" whenever I give a command.
When I give the same command immediatelly, it works seamlessly. These days I end up giving the commands two time whenever I have to wake the device.
The forum solutions were no go and technical assistance from Tenda Nova is subpar and very slow response.
Have you tried this https://www.reddit.com/r/googlehome/comments/a03b9z/google_h… its for google home mini but worth a try
