I recently changed phones from an iPhone 7+ to a iPhone X
I have been using Swiftkey for many years throughout different phones (each year iphone upgrade)
This year I ran across an issue where the words I normally predict is not on my iPhone X anymore.
If you look at the pictures on the iPhone 7, you can tell that the words that are usually predicted is not on the iPhone X
I have even tried to connect the accounts and its still not there.
When I used to do iCloud Backup from old phone to new phone, I dont even have to sign in and get all the same text predictions!
I have attached some screenshots :)
