I switched to uTorrent once BitTorrent introduced ads. Then I noticed uTorrent was BitTorrent in all green, and using the latest versions for about a month, the magnet link still didn't work (across two different computers).That's odd. Magnet links seem to work fine for me though. Maybe try getting the latest build and see if it's still there.
Instead I just went back to BitTorrent and disabled the ads
