Special gems offer bug

This is what I see when I click on the latest offer

Hello ZX10R,

Are you sure you are still connected to Internet? Also, which offer was it exactly?

Sorry for the troubles.

Yes, I am connected to Internet and can play the game. It says Special Gems Offer

Hello ZX10R,

Would you have a screenshot of the Special gems offer announcement?

Hello ZX10R,

Does it happen each time you tap on the special offers button?

Hi Alysea, yes, every time I tap on it

Hey ZX10R,

What kind of Internet connection do you use? Mobile data or Wifi?

Used them both during the day. Mobile initially, wifi later

Hey,

Could you please let me know which device and OS version do you use?

iPhone 6, iOS 9.3.2
