Here are a few points I have compiled using resources and community answers to help clarify and address the issue:
Online Registration: You don’t “download” a workspace—instead (a common misconception among new comers and beginners), you sign up at apex.oracle.com to create one. The registration form requires details such as your name, email, workspace name, and location. Once you submit the request, the system should immediately send you an email prompting you to complete your account setup.
Instant Email Confirmation: In most cases, you should receive an activation email within seconds. If you haven’t received it, double-check your spam or junk folder. Also, verify that you provided a correct and active email address.
Resubmit Your Request: Sometimes, re-registering (or trying again) with the correct details may help. Make sure there are no typos in your email address.
Alternative Option – Oracle Cloud Free Tier: If you continue to face issues, consider using the Oracle Cloud Free Tier, which provides free databases along with APEX. This option gives you more control over your environment, and you can later migrate your work if needed.
Email Filtering: Your email provider might be filtering out the confirmation email. Adding Oracle’s email domain to your safe sender list might help.
Temporary Service Glitch: There could be temporary issues on the Oracle APEX side. If the problem persists, it might be worth checking Oracle’s forums or support channels for any known issues.
