Hi,
I am working on "Sign Up for a Trailhead Playground with Einstein Lead Scoring" under "Prioritize Leads with Einstein Lead Scoring ".

I have followed the steps one by one but stuck at step 7, which asked me to connect my new developer edition to trailhead. 
But I could not find any option under Trailhead playground picklist looks like "Log into a Developer Edition".

I have spent hours trying to fix the problem. Did I possiblly missed any thing? I appreciate it if any one can help me solve this.
