Mobile version is buggier than an anthill, and in a browser not much better off. Constant issues with subs not appearing for a variety of reasons on both platforms. Additionally, they don't seem to have passable servers in North America; I can watch Netflix or YouTube on an equivalent or better resolution without any connection issues. On the (frankly dim) bright side, they do have a good selection of anime to watch, even if just attempting to do so is a headache.
