It's not recommended to run the Starr apps through a VPN, what can happen is that the Starr apps doesn't update the posters or metadata or you can't add new movies/tv shows, it doesn't need to happen right away. but sooner or later it can and probably will happen.
Just run VPN on the apps that actually need it, like your torrent client, and perhaps in some cases certain indexers because of region/ISP restriction.
Please check the indexers rules if you're allowed to use a VPN/Proxy to access their site, being that VPN services often use shared IP it could be recognized as account sharing.
This isn't the same as the tracker, the API/Website scraping happens on the actual site and some indexers don't allow VPN usage on their site.
