As you can see, even though I have a Microsoft account the message saying that i'll be notified if I can migrate still shows
The purpose of this notification is to provide the link to FAQ, so even if you have already migrated your account the link is still relevant if needed. I don't think this is a bug but is actually serving its intended function perfectly fine. The link itself is not used to begin the migration process, but to just provide information about the migration process, purpose, and effects. If you do not want to use the link you can just ignore it and it will have no effect on your game or account.
