I hit the "add to Upwork" button, but only later I realized that the email address I had used to create my profile was not the same which is connected to my Upwork profile.
So I changed in my profile the email address.
I would like to add my certification to my Upwork profile now, but the "add to Upwork" button is not available anymore.
Is it still showing that you have completed the certification within HubSpot?
Can you send along screenshots of what you are seeing? Additionally, if the email address you completed the certification with is different than that associated with your Community user, can you please provide your email address as well?
