Happy to tell you that I completed both (professional and expert) Adobe Analytics in one shot. Special shoutout to @Jennifer_Dungan for being my teacher and problem-solver in many places. Never thought I would complete both exams in less than 1 hour. Thank to all who helped me in this.
I forgot to mention one thing. We migrated our site to new platform and the page load time improved from 8 sec to 3 sec. Since then we started seeing the gap in orders. Do we need to make some changes in adobe launch to load quickly and capture values?
I tested by doing test purchase and used debugger. Also cheeked adobe report and the transaction was seen. The difference is in both no. of order IDs and revenue amount.
