YouTube “Tutorial” is not what app does

Watching the very fast-talking and superficial YouTube video implies that you can click here to perform this and there to perform that, and none of it works well on my brand new MacBook Pro with the lastest OS X update. For instance, the “photo” icon button on the lower left of the right picture does not bring up a color wheel at all. The images zoom in and out seemingly without control, and they appear blurry when done. Nothing explains the pull-down menu that seems to have effects. I was used to editing pretty well with iPhoto, but wanted a better background removal. This works on some things, but not well on others. With the change to Photos on the Mac, I felt that I needed finer tuning. However, the few controls this app offers at the top don’t necessarily do what is shown in the tutorial. Perhaps it needs an update; but $20 is way too much for this flakey app.
