Hi OpenAI team,

I found a login issue when I tried to log in on my iPhone.

Steps to reproduce:

1. Go to the Apps on desktop and click Booking.com app.

2. Copy the link of Booking app and paste it into the Safari browser, then the ChatGPT app will be open; after that, click the Connect button.

3. Got this error when logging in with an email address.
