App Store Connect message: Your account will soon need to be migrated to federated auth

Question

Looks like broken deploy on Apple’s end where they accidentally rolled out an internal page to third-party developers. AppleConnect and Quip are used internally so it’s not surprising to see them mentioned. (The link that is failing to load is behind Apple’s corporate VPN.)

I have contacted Apple Support on phone and they assure me that it is not for developers accounts and I should just ignore it as it is related to Apple Business Manager. And as a confirmation they sent an e-mail to confirm it with some links to help with understanding more about it.

I think it was a bug. Right now when I log in to my App Store Connect, I am not seeing any related error or message on the top portion of my portal. It simply got vanished.
