I'm glad you're trying out the DIGITs BETA, and I definitely want to make sure we get this addressed for you.
I just tried this on an iPhone here, also running 10.2. I didn't seem to have any issues. Is it one specific contact you cannot find on the favorites tab? Have you been able to find others? Also, have you signed out, uninstalled and re-installed the app?
OK... I see the issue. The GUI is a bit misleading to me.
Under "Favorites", you have the '+' and the Search logo next to each other. I hit the search first thinking I will search for the contact and then add them in. I didn't realize Searching meant only searching who is currently in my favorites list. Obviously, the person I'm trying to add wouldn't be in my favorites.
When I click on '+' instead, I do see the contact and was able to add them in.
You can call it user training but that confused me quite. It can very well be just me.
