Hi Adam,
Currently it is generating incorrect links. The correct link should be your profile URL + credentials + credential ID. For example, say you view one of your certificates and see that the Credential ID is 6231DAB619FA8F1. The correct sharing URL in that case would be as below:
https://learn.microsoft.com/en-us/users/adamjsmith1995/credentials/6231dab619fa8f1
Using the above you can manually share your certifications while they are fixing the site.
Please click Accept Answer and upvote if the above was useful.
Thanks.
