Ugh. While I appreciate off-the-road apps, the problem with it is... no structure or organization, or written by self-taught programmers.
The "instructions" on what to do (or how to install) are a complete disaster and I have no idea how to install export-tools from the thread. The "automatic" method is ironically much more difficult than the "manual" method. At least the manual method has step-by-step instructions. Installing the "Unsupported AppStore V2" (which is needed for "fully automatic installation") has no such clear instruction.
I'm a little peeved because I'm a software developer with 25+ years of experience at Fortune100 companies. If you've bought things from Lowe's, banked at Wells Fargo, used Blue-Cross-Blue-Shield, then you've run my code. But... I know how to write instructions just as well as code... and some would argue that the instructions are far more important.
Why Plex doesn't adopt some of the obviously more useful of these apps is silly. Not very forward-thinking.
Sorry, off my soap box. I'll just try the manual method.
