Dex and Smartview cannot connect to my Sony Android TV KD-55XF8505 via WiFi
I get
WiFi-Gerät angeschlossen
but the WLAN Connection fails
though the TV is in the WLAN, and the same as the Note20 is.
Other mobiles, e. g. Note8 and Xiaomi Note 8 Plus can connect via Smartview.
They do not supply DeX though to test.
