You may also want to look into Usenet instead of torrents when you're researching. Sonarr/Radarr/Readarr etc all work (in my opinion) better with Usenet.

You'll need to pay some, but the reliability is amazing, which is extremely helpful for the partner acceptance factor. I pay for two providers (newsdemon is primary and eweka is a backup) and two indexers (drunkenslug and nzbfinder), and everything has been rock solid reliable for years. Download speeds are also MUCH faster than torrents.

Combine this setup with overseerr (or jellyseerr) so your partner can find their own things to download and you might be able to get them back on board.

Plus, no flaresolverr required!
