I'm trying to delete contacts from my Google account that's synced with my Nexus 5. It's synced as a Google account, not using Gmail IMAP or anything like that, but all of the contacts display this message when I try to delete them:
You can't delete contacts from read-only accounts, but you can hide them in your contacts lists.
I don't understand why the Contacts app (default, from Google) is saying my Google account contacts are read-only. How do I correct this problem so I can fully edit contacts from my phone?
