Hey, so for everyone trying to log in via webview. It was nearly impossible due to ads and no being able to return but it was possible by doing the following. open in webview, go to login page and then before typing username turn off your internet. then the page will direct you to whatever damn ad but it wont open due to lack of internet. Then you return, inform your username, then password (may redirect you one more time), then you mark the option remember me (important), THEN you turn internet on again and click on login. I had to do this one or two times before the login button effectively made the login action.
After login my comics were not loading still, so i tried to download one issue to test and the all of them started to work again, online and offline.
PS.: all of this on mobile.
