Issues with magic link session in my Expo app

Expo

I have a monorepo (Next.js web app & Expo mobile app) where I have setup a magic-link based auth flow.

My app's auth flow:
- Choose a valid username
- Provide a valid email
- Then the

join

join

endpoint (which is a Next.js api route) sends the magic link

Here's the specific code:

await auth.api.signInMagicLink({
  body: {
    email: email.trim(),
    callbackURL: callbackUrl || "/me?verified=true", // Use provided callbackUrl or default
  },
  headers: await headers(),
});

await auth.api.signInMagicLink({
  body: {
    email: email.trim(),
    callbackURL: callbackUrl || "/me?verified=true", // Use provided callbackUrl or default
  },
  headers: await headers(),
});

I get the callbackUrl from the request body of this endpoint like this:

const { username, email, inviteCode, callbackUrl } = body;

const { username, email, inviteCode, callbackUrl } = body;

The mobile app also uses this endpoint in my waitlist/signin component.

What's currently working in the mobile app:
I'm getting the magic link sucessfully in email. Here's how it looks:
https://www.beenthere.page/api/auth/magic-link/verify?token=TZLlbsVANKAPomSjMGLsgbaRsjqSjIvhJ&callbackURL=beenthereapp%3A%2F%2Fauth%2Fcallback

What's not working:
When I click on this link from email, it sucessfully opens the app but the validation fails.

Here's the error:

{
  "params": {
    "cookie": "__Secure-better-auth.session_token=**********; Max-Age=604800; Path=/; HttpOnly; Secure; SameSite=Lax"
  },
  "error": "No session returned"
}

{
  "params": {
    "cookie": "__Secure-better-auth.session_token=**********; Max-Age=604800; Path=/; HttpOnly; Secure; SameSite=Lax"
  },
  "error": "No session returned"
}

Has anyone faced similar issues before? What am I missing?
