Can't login to the"niconico"from Account in Settings

[kamaimin]

Thank you for always letting me use it so much.
Regarding the subject of the title
Videos that you been watching in 1080p because you were logged in suddenly became 720p.
I was wondering if I was logged in, so I logged out and tried to log in again.
When I touched "Login", the screen did not transition and remained at the spinning icon.
I have tried reinstalling older versions (4.24-4.40) on other devices and the same problem occurred, so I am raising this as a question.
By the way, when I try to log in using my Google account, I get a message saying that I can't log in because [JavaScript is disabled].

Hi, thanks for your feedback.

I just tested the login procedure and it works fine here for both NicoNico and YouTube. Given the info you provided, it's likely an issue related to your device. You may need to check "Webview Implementation" in your device's developer settings.

For the 1080p -> 720p issue it's likely due to the cookie becoming invalid. A successful relogin should fix the problem.
