I have asked a similar question regarding Power Apps. Is there a link to official documentation, official training videos, and/or highly popular videos regarding Microsoft Flows? I have jumped in and watched a training video. My goal was to learn how to do one specific task. But I felt overwhelmed and I did not know what I was doing and why. I was just following the steps. That might be a good introduction and might give one a feel for the product, but to fully grasp WHY instead of just the HOW, it requires something better as an introduction.
