My contacts row used to show up in the share sheet and after upgrading to ios 14.1, it's gone.
I dug around and found out you're supposed to be able to toggle Siri & Search -> Suggestion when Sharing, but I've tried that and it's gone/not coming back. Hopefully that will work for you Drakena :)
I've rebooted, I've upgraded to ios 14.2 and still gone. I use this almost EVERY DAY and while I see mostly people complain about it, how about making sure it works for those of us that use it often? It's really genius - one click to share. So easy.
