Where does the bug appear (feature/product)?
Cursor Mobile (iOS app) / Account, billing & login

Describe the Bug
I can’t log in to the Grok Bot / Cursor iOS app on my iPhone Air running iOS 27. The login screen shows the error “登入超時，請重試。” (Login timed out, please retry.). The desktop version works fine with the same account.

Steps to Reproduce

  1. Open the Grok Bot / Cursor iOS app on iPhone Air (iOS 27)
  2. Try to log in
  3. After a while, the error “登入超時，請重試。” appears and login fails

Expected Behavior
Login should succeed and enter the app, as it does on desktop.
應能正常登入並進入 App，與電腦版一致。
