You are not alone in this assessment Matt and it was the first question I asked on the old forum the day I purchased Blocs. Norm is well aware of this problem and it partly results from the rapid pace of changes.
I expect the final version of 2.3 to become available in January and Norm says documentation will improve significantly after the release of 2.4 Blocs and inserting code from other sources - #15 by Norm
In the meanwhile it looks like we’ll have to dive in and experiment. When we break things or run up against problems we can ask here for help. I’ve searched on YouTube for tutorials but often found the interface looks totally different, even compared to Blocs 2.0.
