Best 2017 CI 3 Tutorials for Newbie?

Any recommendations for online articles/videos on CI 3? There is a lot of CI tutorials out there and most are old.  I am a mid-level PHP developer but new to CI.  Any recommendations are appreciated!

I just used the CI  Tutorial
That explains how things work in CI and for me that was enough to get started and do some simple project.

I have worked through some of those tutorials but they are limited if you run into issues and need to troubleshoot.
