Does the “I’ve completed this challenge” box become active when you paste your link in?
If so, is it giving you any error or is the button just unresponsive?
Is your link similar to the example they give?
Have you tried a different browser at all or do you have extensions/protections that might limit the checking?
Hope you get it working soon and let us know if it is still giving you trouble.
The “I have completed this challenge” box becomes active yes.
I don’t have any error messages coming up, the little circle just remains empty.
My link is similar to theirs. (https://codepen.io/martin-ruscade/full/XWbKrgo)
I tried chrome, microsoft edge and internet explorer.
