I am on Step 6, and I am able to download the Google Drive file, but it opens in Numbers in my Mac. I am not able to avoid this process, and even when I export the Numbers file to a CSV on my desktop, it still does not transfer to Salesforce properly. It says unmapped, but there is nothing I have done wrong on any previous steps in any of the previous labs.
Sorry you're stuck but there's almost always a pretty easy fix! Do NOT try to start all over again, uninstall Max's Pitch Package, etc. That can make it worse. There's a 95% chance the same snag/fix is listed & answered in the Help FAQ. But if you can't find it there, post your problem here.
Make sure you post in the right category below & be sure to include a screencap showing the issue!
