I cannot add more than 1 favorite in Phone app in iOS 14

Seems to be fixed in iOS 14.2. I had the same issue earlier.

What worked for me:

• Delete the previous favourites and add them again.
• While deleting the old favourites, you might encounter some numbers keep coming back, but persist with it and delete them all
• Then add new favourites
• Hopefully it should work.

Seems this may only be occurring for those setting up the device as new. I have my iPhone 12 Pro and set it up from my iCloud backup of my 11 Pro. I just attempted to add a couple of Favorites, and they added just fine. I went in and deleted one of them and kept the other for a short period of time and that worked as well. I just went in and deleted the second added favorite and that worked as well. I'm using iCloud for contacts. I'm using iOS 14.1.

Same problem as you. Setup iPhone 12 Pro as new without using the iCloud backup restore and having problems with favorites.

I can add multiple favorites sometimes but then when I click it doesn’t dial. And if I kill the phone app and reload then they are gone.

An additional detail I’ll add is that when I am selecting the contact to add as a favorite and then choose “Call” option, the drop down has duplicates or the primary number for that contact and only one of them seems to work for actually being able to dial.

I use iCloud for contacts saving and confirmed in contacts app there isn’t a duplicate contact or duplicate of the number within the contact. One of the contacts I had previously as a favorite has the star icon next to it in contacts indicating it is a favorite but does not actually appear in favorites.
