I have been seeing this in my User Accounts tab for the past 24 hours (well, almost).
Account Association Disabled
While the network is being migrated, account assiciations to Meta have been disabled.
(Note: Yes, it is account assiciations, you read that right. :)
This happens to all other user accounts as well.
My question: How long does it take for the network migration to complete so I can see those other related accounts in StackExchange sites?
