Hi Walter Scate,
Thank you for reaching out to Microsoft Q&A forum.
We understand that you have been trying multiple ways, but it is not working for you, I request you to take the following steps before you try to activate a sandbox:
- Log out from all Microsoft accounts in your browser, clear the cache and try to login to your Learn account using the proper credentials.
- Browser Compatibility: Ensure that you are using a supported and up-to-date browser.
- Browser Settings: Check if your browser is blocking any necessary cookies or scripts.
- Incognito/Private Mode: Try using the incognito/private mode in your browser to rule out any cache or cookie issues.
- A simple restart can resolve various issues. Restart your computer and try activating the sandbox again.
