Expected behavior
Contacts and profile labels are synchronized.
Actual behavior
Contacts and profile labels are not synchronized.
Explanation
Deleted chats are now synchronized, which is a huge improvement if you use a profile on multiple devices. Sometimes, after deleting a chat, you also want to delete the respective contact. Unfortunately, this has to be done individually on each device. It’s the same when changing the profile label. Therefore, I think it would be better if the contacts and profile label were also synchronized.
