Seems that 965 doesn't find my WiFi network, the same as Enduro 2 and Epix 2 use without problems. Is there something wrong with WPA3 or whatever?
Odd that its not on the list of fixes but there was a version change on the WIFI firmware version that someone posted on the Beta forum.
Just tried to sync just now and it worked with WPA3 being turned on on my network with the 4.12 firmware.
