Hello, @Akbar Fadilah !
How do I access my Learn profile in the Azure Portal?
It looks like you're signed into the portal under the wrong subscription. You'll need to first activate the sandbox (this will give you a Learn directory you can use) and confirm that the default directory is set correctly:
If you sign in to the portal and are in your own subscription (or you sign in to your subscription and end up in the sandbox), one of two things might be wrong. Either you haven't activated the sandbox or your Azure settings put you in a default directory. You can change the directory by selecting the Directory and Subscription filter button on the toolbar along the top.
The button opens a drop-down list where you can select the correct directory. You can also change the Set your default directory setting to the directory that you work in most often.
When you activate the new sandbox, the old sandbox environment is destroyed, along with any resources created in it.
If you have additional questions, please let me know in the comments and I would be happy to help you.
