【iPhone / iOS 17 or later】Login button is grayed out and cannot be tapped (caused by popup blocker)

  • iPhone (iOS 17 or later)
  • When logging in using the Safari browser           

           

  • On some iPhone devices, the login buttons for Google, Yahoo! JAPAN, etc. may not be clickable (they appear greyed out).
  • Required information may not be displayed.
  • The screen may turn white and display nothing.  

 

  • If the "Block Pop-ups" setting is enabled in Safari, the browser may block the pop-up window required for login, preventing the authentication process with external services (such as Google or Yahoo! JAPAN) from starting. As a result, the login buttons may become disabled.

 

  1. Open the [Settings] app from your home screen     
  2. Select [Safari]     
  3. Turn off Block Pop-ups     
  4. Restart Safari and access the reservation page again    
    *A screen like the one shown in the image below will appear.    

   

        

Please try the following steps:       

  • Try accessing the page using another browser (e.g. Chrome)     
  • Restart your device
  • Clear cache in Safari
