How to fix issue on using sandbox during exercise?

@Aldrin Bugas , Firstly, apologies for any inconvinence with this issue.

Just to clarify, which Azure fundamental module are you practicing? does this issue occur only on this module/unit or other modules as well?

If you haven’t tried this already, please try the same on different browsers, and check if you experience the same issue.

Why can't I sign in to use the sandbox?

As kobulloc-MSFT, my colleague mentioned on the above thread (copied here).

This has been an ongoing issue that has been affected a small but significant percentage of users. The sandbox team has been made aware of the issue however they have been unable to reproduce this locally. While a fix was released last month, there are several dependencies which complicate this (including the email/account type used) and it appears that many people are still running into this.

If you encounter this issue, we are asking for the following information to help create a new fix
(post the referenced thread):

·       Your Learn profile ID (we can get this if you post a comment)

·       Repro steps to help isolate the cause of the issue (including what type of email account you are using)

·       We may request additional information via email as we continue to investigate this

Thanks for your patience as we address this issue.
