To turn off ads and offers, open Options > Preferences > Advanced. Here you’ll find a large list of flags for the app and a filter box. Search for and disable the following flags:
- offers.left_rail_offer_enabled/left_rail_offer
- gui.show_plus_upsell
- offers.sponsored_torrent_offer_enabled/sponsored_torrent_offer_enabled
- bt.enable_pulse
- gui.show_notorrents_node
- offers.content_offer_autoexec
These flags may be named slightly differently depending on which version of the app you’re using. Be careful when editing things if you’re not entirely sure what they do.
