Hi Jeffery Smith,
Thank you for reaching out Microsoft Q&A forum.
It sounds like you're dealing with subscription and access issues that can indeed be frustrating.
Here's a step-by-step guide to help you manage your subscriptions, avoid the repetitive sign-up prompts, and minimize the CAPTCHA challenges:
1.Please go to https://portal.azure.com and sign in with your Azure account credentials.
2.Please click on your profile picture or name in the top-right corner, select "Switch Directory" to ensure you are in the correct directory, and then go to "Subscriptions" to view all subscriptions associated with your account.
3.If you see an alert saying, "No Subscriptions," it means you're not in the correct subscription; please identify the active subscription for your learning account, typically the "Concierge Subscription" provided by the Azure learning sandbox.
4.If you have multiple subscriptions, please select the one that matches your learning account (e.g., the "Concierge Subscription") and set it as your default to avoid repetitive sign-up prompts.
5.In the "Subscriptions" blade, select the subscription to cancel, click "Overview," then "Cancel Subscription," and follow the prompts to complete the cancellation process.
6.Your course progress is typically linked to your Microsoft Learn profile, not to a specific subscription; however, to be extra cautious, please make sure you are signed in to Microsoft Learn with the same account used in the Azure portal and check your progress on Microsoft Learn at (Training | Microsoft Learn).
7.Unfortunately, CAPTCHA challenges are part of Azure's security measures, especially in sandbox environments; to minimize these, ensure a consistent and stable network connection, use a browser like Google Chrome or Microsoft Edge where you are consistently logged into your Microsoft account with fewer privacy restrictions, and consider using a trusted device that Azure might recognize more reliably.
