Did you ever find a solution? I have the same problem, just worse after the Nougat Update for my Huawei Mate 8.
Whenever I edit on the device (tried Huawei Contacts app & Google Nougat Contacts app), the long Notes field gets truncated.
When I edit in the browser
www.google.com/contacts, I can edit, it sticks there, but still doesn't get synced back to the device... On the device it looks truncated, even though in the cloud it's there.... Frustrating!
My friend with a Mate 9 has the same problem.
