I'm using Oneplus 5 OS version 10.0.1, Deco App version 3.2.13, firmware version 1.1. 0 build 20221102 rel 66085. 

Here's the screen recording how to reproduce the bug.

  Other minor bugs I've also noticed:

* Not only the Guest SSID the deco will not remember, also the security. It will go back to WPA2 instead, I already save the WPA2/WPA3 Personal. 

* New device notification even that device is already connected to the router before. 

* When I checked the notification about the new device, I cannot see it. It seems the log stuck and never update the list. 

* Some devices appear offline even they are connected and functional. The online list just randomly tagging devices offline every few seconds.

* Speedtest by Ookla inside the deco app is gone.

This bugs I've encountered are not present on the older deco m5 before the upgrade.

Thank you very much. For me, the Ookla's Speedtest is more reliable than Deco lab's speedtest because I can set the server nearest to my location. Before the upgrade, I got exact speedtest result using Ookla based on my 600Mbps plan. The Deco lab speedtest, I only got 200 to 300Mbps. It's very useful feature especially if you don't have a computer or wired connection to do the speedtest.
