User is lost when being sent to my app from external pages

Example:

Somewhere on external site

<a href="http://my.web.site/some/page">Go to my app</a>

My page:

const MyComponent = () => {
  return (<><h1>Hello</h1></>);
}

export default withAuthUser({
  whenAuthed: AuthAction.RENDER,
  whenUnauthedBeforeInit: AuthAction.SHOW_LOADER,
  whenAuthedBeforeRedirect: AuthAction.SHOW_LOADER,
  whenUnauthedAfterInit: AuthAction.REDIRECT_TO_LOGIN,
  LoaderComponent: FullPageLoader,
})(MyComponent);

SSR:

export const getServerSideProps =  withAuthUserTokenSSR({
  whenAuthed: AuthAction.RENDER,
  authPageURL: "/login"
})(handler);

my handler:

...
console.log("user", context.AuthUser);
...

produces:

user {
  id: null,
  email: null,
  emailVerified: false,
  phoneNumber: null,
  displayName: null,
  photoURL: null,
  claims: {},
  getIdToken: [Function (anonymous)],
  clientInitialized: false,
  firebaseUser: null,
  signOut: [Function (anonymous)],
  serialize: [Function: serialize]
}

And if I refresh the page - everything loads correctly. No idea why user is lost when coming from external pages. Tried searching PRs and Discussions - can't find anything...

This behavior is likely determined by your cookie's SameSite setting:

I assume you're using Strict? Try Lax and see if it changes the behavior.
