Can you tell me what phone model and Android version you have to try to reproduce the issue?
Meanwhile I opened an issue on github https://github.com/lgallard/qBittorrent ... issues/111
to track it.
On the other hand, did you check you don't have Chrome set as the default app for .torrent files or magnet urls?
After testing with the site itself, other sites, and other RSS feeds, I have narrowed the issue down to a specific site/feed.
The feed/site that fails is nyaa.se. Selecting an item in the feed, or even selecting the magnet or torrent from the site itself in Chrome sends Chrome into an endless loop of trying to download the file but being unable to. Sorry for not having tested thoroughly before posting this.
For reference, I'm using an unlocked HTC 10 running MM.
I still have my older M8 sitting around. I'll try if there this evening and see if the behavior is the same.
