Hi Vikram, Error 404 in Part 3: Brand Portalhttps://experienceleague.adobe.com/docs/experience-manager-learn/assets/sharing/brand-portal.html?lang=enWalk throughs of the AEM Author and AEM Assets Brand Portal integration.  Maybe it could be the cause of the problem. 

Hi, I've taken a course in the EM Assets, link as below:https://experienceleague.adobe.com/?lang=en#dashboard/learning In the "AEM Assets Skill Builder" which runs for 5 hours, blue check marks are acquired on all presentations, but somehow it said only 41/43 completed. Any idea?
