Ask HN: Anybody else having dev.azure.com/vscode auth issues?

Anybody else suddenly having trouble logging in to https://dev.azure.com/vscode to update or publish a VSCode extension? I can login to my Microsoft account, but whenever I then navigate to dev.azure.com/vscode, I need to login again and I get redirected to https://login.microsoftonline.com/common/federation/oauth2msa, where it says:

> AADSTS50020: User account '[myemail]' from identity provider 'live.com' does not exist in tenant 'Microsoft' and cannot access the application '499b84ac-1321-427f-aa17-267ca6975798'(Azure DevOps) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account.

I really need to push an update to https://marketplace.visualstudio.com/items?itemName=mastro.mastro-vscode-extension and my personal access token is expired :-(
