@DrMuhammad @Thelonewolf If it's just questions about why is the MangaDex extension for Tachiyomi not working properly, the answer is indeed that our api server caching is messed up and will lead to some inconsistencies between Tachiyomi and the website. There's nothing else I can say about it except that we're aware, we're working on it, there's nothing you need to or can do, you'll just have to wait until it's done.
That all has nothing to do with this thread, however. This isn't a support thread for general users, this is developer news. Do not read this thread thinking there's anything here that would help fix your Tachiyomi issues.
