Apologies for the inconvenience with this issue.
Based on my understanding, you're practicing AZ-900/AzureFundamentals (3 modules listed) but you're facing sign-in loop issue.
Edit: Copied the solution that worked for @Chan, CH Calvin (Thanks for sharing)
I have fingered out a temporary workaround to get rid of it. After clicking "activate sandbox", go to do manual sign-in in Azure portal (portal.azure.com). Once it is done, go back to the learning portal and click "sign-in" again, the Cloud Shell will appear successfully in learning module.
Why am I unable to sign in when using the Learn sandbox?
We are currently working on a fix for this issue and are collecting information from those who are experiencing this as well as providing updates here:
Where am I seeing this?
- Subject: AZ-900/Azure Fundamentals
- Modules:
Microsoft Azure Fundamentals: Describe cloud concepts
Azure Fundamentals: Describe Azure architecture and services
Azure Fundamentals: Describe Azure management and governance
Thanks for your feedback! Please be assured that we have relayed your feedback internally to our Azure Learn team,
