So, as you all know Samsung is making huge collaborations with Microsoft.
They've removed Samsung keyboard prediction/dictionary sync from the Samsung cloud.
Could it be that the SwiftKey will replace Samsung Keyboard?
SwiftKey has been bought by Microsoft and it's their main keyboard.
I've been using the keyboard since 2014, it's the best in my opinion.
Swiftkey could replace Samsung keyboard at some point. However Samsung may prefer to offer the choice. For those not familiar see more here https://support.swiftkey.com/hc/en-us/articles/204609851-How-to-use-the-Microsoft-SwiftKey-Keyboard
However keyboard syncing may not suit everyone https://androidcommunity.com/samsung-suddenly-stops-keyboard-sync-to-cloud-20200417/
