IWatch show no fav and “ reset sync data” appears to do nothing. Name card accurate, using my name card for iCloud …

Tried nearly everything, reboot, unpair repaired, iCloud card for my address card , etc etc etc

I finally read online what it may be and it worked and was simple. On the iWatch series 7 all I had to do was LONG a press the Wi-Fi symbol after swiping up which brings it up into view. After a long press on the Wi-Fi it brings up my home network and mine was NOT connected even though blue tooth was on and Wi-Fi signal showed on and green rectangle showing Bluetooth connected to my iPhone. I never after 5 watches counted Wi-Fi with a long press and connected it. Hope this helps someone as about 10 other things it could be. FYI, pressing resync “immediately “ added everything into fav on iWatch and updates contacts instantaneously.
