Phone Model - iPhone XR
Version iOS 14.4
Key Issue: After upgrading from 14.3 to 14.4, SwiftKey fails to work on any application (Microsoft Office 365 mobile applications, WhatsApp, native text messaging, etc.) even when it is the default keyboard. I've deleted and reinstalled the application, restarted my phone, and the Board will flicker to SwiftKey but then switch automatically to Apple's native keyboard. I've installed other third-party keyboard applications to test if this is an issue for them (e.g. Fleksy and GBoard) and run into no issues. Seems to just be an issue with SwiftKey.
Is there a recommended fix for this? This never occurred or was an issue prior to installing the 14.4 software update.
Any suggestions would be appreciated.
