'loading' is always true in production build

[Gabsys]

Description 🐜

The loading in const [session, loading] = useSession() is always returning true in production build. Works fine in development mode though.

Is this a bug in your own project?

No

How to reproduce ☕️

import { useSession } from 'next-auth/client'

export default function Page() {
   const [session, loading] = useSession();

   if (loading) return null
   return (
      <p>Session valid</p>
   )
}

2. npm run build
3. npm run start

No, I am afraid I cannot help regarding this

I cannot reproduce this. You will need to provide a more detailed reproduction or I'm going to move this to discussions. You can use any of our CodeSandbox templates for convenience (it was available in the issue form you filled out.)

Managed to locate the culprit. Not NextAuth's issue but a package's css file that is imported which spoil the app for some reason.
