Truenas apps are mere docker containers configured by someone else in the community.

If you turn them into a customized app, you gain all the docker options control and can change the image. It’s all up to the app maintainer to switch to the correct image, or yourself to do it manually.

Don’t blame psychology, in this analogy the whole ordeal was rape. Plenty of economist still try to pass as psychology science a bunch of bullshit that was debunked half a century ago or is straight up pseudoscience from charlatans.
