Not that it is any surprise at this point, but I was testing adding magnet links from a mobile browser page to my utorrent via the uTorrent Remote app on my android phone. I was pleased to see the app had associated magnet links with uTorrent Remote (or did after I told it which app to use permanently), but when I tried to then launch the app to see whether the torrent was downloading, I could not log in. Of course, at this point, I have to assume the 28993 build crashed just as it did when I tried magnet links locally.
