Hello, 

I am new to the Saleforce world and I am soaking up all I can.  I figured out how to get into the new salesforce app for both my trailhead, production for work and sandbox for work. I also logged in as a Community Partner user. The problem is, when you log into the Salesforce App as a Community Partner, it is obvious that it is not the new Salesforce app. Being new, I am not sure how this was created?

Any ideas or where to start?
