I am unable to claim my certificate.
I completed all tasks, so unsure what mandatory stuff is pending.
Here is my url Learn to code with Scrimba
@roku explained the issue on the Discord development channel:
Our certificates are currently running into an issue where it’s not showing your name and is marked as “Not yet completed” in the completion date. We’re in progress of fixing this up. Once fixed your certificates should be updated with the correct data.
Also, congratulations on completing the JS course! 
Thanks for the info @gassim!
I think it might be working now. @Suyash_Sreekumar If it’s not working still you can manually mark the module and lessons as complete to see if you can claim it.
