If your SwiftKey keyboard is set to use Gestures then you won't be able to Flow. We offer you the choice between one or the other.
You can enable/disable SwiftKey Flow by following the below steps:
- Open the SwiftKey Hub
- Go to the 'Settings' pane, tap 'More'
- Tap 'Typing'
- Select 'Typing & Autocorrect'
- Tap into 'Gesture input'
- Check/uncheck Flow
