I’ve been using TrueNAS Scale for a while now, but have never actually come across any official documentation/repository/possibility to file bug reports for TrueNAS Scale apps marked as “Official” in the available applications (e.g. Plex Media Server, Home Assistant, etc). Have I just miraculously missed it or do these apps actually not have any form of documentation or support?
The Scale apps documentation, containing a couple of guides for a small set of apps.
https://www.truenas.com/docs/scale/scaletutorials/apps/
The app repository for the official apps.
https://github.com/truenas/charts
Also I highly recommend using Truecharts app catalog. They have an extensive list of apps available, and the support on their discord is excellent, in my opinion, although they also appear to be lacking in the documentation department mostly.
