I love what you're doing but I can't seem to download TUs. Whenever I tap on the download button I either get a "protocol not supported" message or nothing at all. I've tried restarting, cleaning my cache, scanning for viruses, etc and nothing has worked
That's the wrong button There should be 3 buttons, hover over one of them for a second and a tooltip should tell you what it does. The icons are bit misleading. Next big update will fix such design flaws.
