We understand that you are having problem with loading while using external sources such as Mangafox, MangaHere, KissManga, etc. It is because for the past few months, many popular sources have tried to block manga reader apps like Manga Rock from accessing their site. That means you may experience pages not loading / downloading properly.
Please note that Batoto source is no longer accessible. For more details, please take a look at this article.
Therefore, we advise that you switch to Manga Rock source as your main source. Not only the source is a lot more stable compared to others, we are building up this source to be the most stable source, faster loading, with extra content such as editorial collections / author spotlights so you can discover more manga to read etc. Please use this source to continue reading in the mean time, we truly appreciate that!
