Can’t read books on safari
I tried reading early releases on my safari app like I always do but every chapter I click on says I’m using a j-club app that is no longer supported. It’s also not accepting my password.
Can you post screenshots? I assume you're trying to use the old website or old app which have both just been retired today.
If the new app doesn't support your device then you could try https://forums.j-novel.club/topic/3353/yet-another-pwa-jnc-client?page=1 as an alternative to the regular website.
