I’m on the same situation. Got everything completed on Apr 18th, then an update on the GCMS portal saying final decision in progress. After that I got my CoPR number on Apr 24th, still waiting for the P1 email. Based on what I could see, these are different teams who do the documentation check...
Did you get your ecopr already? I’m stuck waiting for the P1. Got everything completed on the tracker on Apr18th and my CoPR number on Apr 24th. Frustrating to see everyone else’s process moving forward while I’m stuck waiting.
