Even tho I completed the course I still can’t access the certificate
You need to go to your account settings to claim your certificate. Before you can do so, you also need to agree to the Academy Honesty Pledge.
To make your certificate appear in your profile, you need to have your profile, your timeline and your certificates set to public. If you want your name to appear on your profile you also need to have your name set to public.
Here I kept some of the settings to public to claim the certificates and you can see that freecodecamp mentioned Your certifications will be disabled if set to private and also accept Academic Honesty Policy
HOPE THIS HELPS
