How long did it take for the 241 to show up? It might take a bit to get the 1,907 to sync --that's quite a few contacts.

Try a New iCloud Session:

Log out of iCloud, and then try this once more. Important: Enable Contacts in iCloud settings on both devices. Elsewise it won't sync.

The automatic sync of contacts from my phone to my computer is not working.
