I have some idea that the devs got DMCA notice from some company and they are trying to shutdown the forks as well. I also read that some extensions won’t work or need to be added from unofficial sources. So my question is how to get back to the smooth experience as before with trustworthy extensions and forks. If there is already a post or link to it, do guide me to it.
Basically, the repo for the extensions has been nuked by DMCAs. You can switch to a repo hosted by a third party to bypass it. I’m not gonna link one here because I have not looked deep into who’s a good host. But you should be able to find one with some searching.
Tachiyomi also released a statement here.
Do a search for keiyoushi on GitHub
Let me also add that you have to be on the latest version of tachiyomi to add a custom repo like keiyoushi
