How do I confirm my MS Learn admin account is properly synced with my organization?

Hi OviyaSharon​ - if your achievement code looks similar to the image below, where after the "?" you see the OCID as a location belonging to your organization, and the 6-digit redeem code (different for every link generated) then you should see the performance metric attributed to your organization. 

Note: redemptions are collected for 1 month and then updated in Partner Center mid-next month. If you were to redeem a code today (Sept 23) you wouldn't see that data in Partner Center until about the 10th of October when all of September's data is listed. 

If you log into your Training Services Partner dashboard in Partner Center, you'll see a "details" button. That will generate an xls that shows the redemptions for each code (class) you created and were redeemed.
