Login failed on ChatGPT app

Hi @phungphancong1590,
From the screenshots, it looks like the mobile flow may not be using an already logged-in ChatGPT session, because it shows the “Log in or sign up” screen before the “Frame load interrupted” error.
I tried opening the Booking.com app from the Apps section while already logged into the ChatGPT iOS app and I couldn’t reproduce the issue. For me, the Booking.com app opened normally.
Could you please confirm:
whether you are already logged into the ChatGPT iOS app with the same account
whether the Booking.com app works if opened directly from the Apps section inside the ChatGPT app
whether the error only happens when opening the copied link through Telegram/Safari/deep link
whether Booking.com connects normally on desktop
