It appears that TP-Link upgraded their Android network management app.

Now I cannot connect to my existing network. It wants to start the setup all over. 

X20 router and mesh network are working with WIFI 6, but I cannot connect the TP-Link app as I have done for years.

Both cell phone and laptop connect to WIFI and internet as always.

Can't tell you X20 the hardware and software versions because I can't get the app to work!

Deco app version 3.10.8.

Is there a solution or work around? Can't find anything here or online.

Thanks
