This is probably a silly question, but before I spend more time trying to troubleshoot things, I figured I'd ask and then bow away in shame
I'm trying to connect Marketo to the Developer Edition of SFDC I got as part of Trailhead. Mostly to play around with getting things set up and testing how it works with the sync (specifically for MSI purposes); however, I get here and am stuck:
Basically, to assign a new user, I need to select Salesforce as the "User License" and the option to do so doesn't appear. Is this a limitation of the Trailhead dev environment?
