Swiping doesn't work with Excel for Android

Is there a compatibility issue between SwiftKey and Excel? I configured SwiftKey to type by swiping. I hadn't experienced any issues until I tried to use it to enter some text in Excel for Android. The keyboard doesn't allow me to enter text by swiping, only by pressing every letter. I'm new to SwiftKey. So far I have always relied on Swype, which works seamlessly with Excel for Android.
