Since upgrading to version 24 of the game, I am not able to use keyboard shortcuts in any of my iOS devices. I test that in iOS 10,11 and 12 on iPhone 6s , 7, XS max pro and iPas pro. The keyboard shortcuts are working in all other softwares with no issue. I contacted Apple support last week and they refer me back to SG and I should report it to you guys.
I hope that will be solved soon.
