Every so often, maybe every few days, my swiftkey resets itself. Whenever this happens it tells me I need to finish installing swift key and it says I haven't completed the 3rd stage of your installation process. I follow the set up wizard every time, sign into my swift key account and personalise my keyboard but it still resets a couple of days later. It's getting kind of tedious constantly putting in my preferences again and because it forgets all of my typing history my predictions aren't very accurate a lot.
I have a HTC 10 and it works off android.
