Swiftkeys now showing Emoji in iOS 13 &Plus

I have a new iphone since a few days, the Iphone 11 pro max & ios 13 was pre-installed. But when SwiftKey is installed, none of the Android 10 emoji shows up, i just have the emojis up to Android 9. Without they keyboard the emojis are showing up. A known person of mine uses SwiftKey on Fmwhatsapp in Android 10 too and her emojis are all showing up but she has a Huawei P30. Is this problem devide-specific? What can i do that the emojis will show up? I don't want to have wasted my money on the new phone, SwiftKey is the only keyboard i can deal with..
