How to use Cloud Shell in Microsoft Learn Sandbox

Question

I'm attempting to do the following lesson:
Exercise: Create a static HTML web app by using Azure Cloud Shell

The learn.microsoft page states "Sandbox activated" and I'm able to go to the Azure portal and swap to the "Microsoft Learn Sandbox" directory/domain. Clicking the Cloud Shell icon in the top nav bar pops up the iframe on the bottom of the page saying "Welcome to Azure Cloud Shell" and prompting between Bash and Powershell. Regardless of what is picked, is proceeds to a "You have no storage mounted" message with the buttons to Create storage or Cancel. Creating proceeds to fail with the following 403:

{"error":{"code":"AuthorizationFailed","message":"The client '[removed-email]' with object id '86a864da-d92e-4b37-a985-c53a6aa8b0c7' does not have authorization to perform action 'Microsoft.Resources/subscriptions/resourcegroups/read' over scope '/subscriptions/7634b321-e0aa-40ed-a594-0ef3b7904533/resourcegroups/cloud-shell-storage-eastus' or the scope is invalid. If access was recently granted, please refresh your credentials."}}  
Can't create a storage account. Please try again.  

The only troubleshooting tips I've managed to find involve clearing cache/cookies, trying in incognito mode, and using a new sandbox instance. Trying in different browsers gave the same error, even trying with browsers on a different PC (including Edge). I let the first sandbox expire and a few hours later started a new one, same errors.

Microsoft Certification Program is supported on their own forums. I'd try asking for help with course issues in dedicated forums here. (Participate\Ask A Question)
