Hi @Michael_Bade ----- Thank you for touching base with me and sharing these observations you have made. The insight is appreciated!
When you paused during the backup restore, did you by chance “sign in” and configure a new install? When I had you rename the “Roon” folder to “Roon_Old” this action moves the previous DB aside so when the application is launched the next time a restore will reinstate a previous version of the DB and “signing in” will generate a new DB.
In regard to the iTunes content that Roon started to watch, if you do not want that content in Roon I would just disable/remove that watch folder and just keep watching the “high-quality files”.
