Hello,
I recently downloaded the latest update of Swiftkey, so I'm currently running Swiftkey 2.0.0 and iOS 10.3.1.
The problem is that since this update, the prediction & autocorrect feature doesn't work anymore (feature that is the most important for me).
The "autocorrect" button is switched on in my settings, I tried to switch off/on my phone and to uninstall/reinstall swiftkey, to log off/log in swiftkey (also, since this operation, I can't log in anymore with facebook, same problem than this post : https://support.swiftkey.com/hc/en-us/community/posts/115002075825-Can-t-login-to-SwiftKey-Account-with-Facebook?flash_digest=2a74e1df58f09ec0ef67ccd861729391949f6864&page=1 ) , but nothing works...
Here are some printscreens:
