Hi I am encountering issues when attempting to sign in to a personal Azure account after linking with professional Azure accounts.

The following error occurs: Error 500121 while using the Authenticator app with the personal Azure account. The Authenticator app works for other Microsoft services (such as Outlook and account profile access), but no notifications are received for connecting to Azure specifically.

Additionally, the "Use a verification code" option requires a 6-digit code, while the Authenticator app provides an 8-digit code.

Efforts to re-enroll the hotmail.com account in the Authenticator app have not resolved the issue.

Stack details:
Error Code: 500121
Request Id: 8ba08084-d2ea-40d8-af69-c6d8ecb00b00
Correlation Id: feb1b358-fd39-4e44-a893-c8e61c42797e
Timestamp: 2025-04-22T21:39:42Z

Any help would be appreciated. Best Regards
