Anime Lib - Watch and Download Anime App Reviews

I dont know if its just me but I have an issue with some video playback. Like specifically I attempted to watch Hellsing and the video wouldnt play but attempting to watch another anime it gave me no problems. Is this a bug or...

I love animelib, I use it almost all the time. Only paying $6 for unlimited anime, worth it for sure. But of course there are some flaws, that can get kind of annoying later down the road. For example, some series in certain servers will not let me download one or more episodes, as they will come up purple in my downloaded list, signaling that it didnt download correctly. Im not sure if its my connection, but I just cant watch certain episodes because they just come up as a black screen. Also the fact that if I resume an episode, it starts back from the beginning. I mean it doesnt effect my watching, its just slightly annoying that I have to find where I was before. Please fix this, it would make this app so much better. Im not sure if its just my device(an iPhone 6) but I cannot download anything unless the app is open. Please fix that as well, sometimes I dont want to wait 30+ minutes for my series to download. Thank you so much for this awesome app, fixing these issues will just make it even better^^

It is very unreliable about downloading. I can never seem to download an episode, it says it is downloading but then the download stops. Very upset about this.
