We are not happy about the permissions handling either, but we don't know of a better way to do it unfortunately.

We have automatic season splitting handling. But it is a manual process to add the handling of that. What anime is so I can look into it?

We discontinued doing the centralised mappings/corrections for crunchyroll, because it is by far the messiest page. The splits of the seasons make 0 sense. It is quite a pain to keep track of the series as every country has a different selection and you have to hop in a VPN all the time. They already changed their identifiers in such a way, that we had to do everything from the beginning 4 times. It is quite a manual process as specially with crunchyroll where even the users do not understand it, there were a lot of wrong corrections requests that we had to decline all the time. So we stopped doing it. Crunchyroll is probably one of the worse tracking pages we have and you are right about that. It is a lot of work so we only keep track of the corrections for a small list of websites.

These Problems can not easily be solved. So thank you that you at least gave the extension a try.
