This plugin doesn't make any sense. I've never heard that anyone divides their animes into seasons. But that's exactly what this plugin does. e.g. although all Dragonball episodes are in one folder, the plugin makes Season out of it and so everything is displayed wrong and episodes are not found. For me a working anime plugin would be a reason to get a premium from the emby, but so I see no reason. Since I only have animes and exactly there this plugin completely fails.
I ask you to completely overhaul this plugin. ´Anime are not packed in Season.
Never use the pictures from Anisearch . These pictures are in such a bad resolution that it makes no sense to crwalen them.
Then anime is not just film and series. Anime also has so-called OVA, Bonus, WEB, and OAD.
