Assalamu'alaykum, when I click "Next Surah", it doesn't go to the next Surah but it either go to the previous Surah or stays in the same Surah but at the beginning of the Surah.

Clicking on "Next Surah" at the end of some of the surahs in some of the later Juzs don't work. They take you back instead to some of the earlier surahs.
