Thanks, I checked the document, but it doesn't solve my problem. I think I needed to give you more information about my case.
I have 2 accounts at learning.microsoft.com:
******@endtoend.com.mx (as a "personal" account)
******@endtoend.com.mx (as "work" account)
I have 2 MCIDs with current certifications:
7190363 - linked to my REAL personal account ******@outlook.com
992643851 - linked to my work account ******@endtoend.com.mx BUT in learning.microsoft.com it is labeled as "personal"
You are limited to having only one "personal" account, I cannot add my 2 MCIDs to my profile.
