about 10-15% of the time, my iphone 5, latest ios, Word Flow doesnt come up as my keyboard - its reverting to the stock IOS keyboard.
Another 10% of the time, wordflow keyboard starts when Im in an app that needs text entry, but the keyboard doesnt come up at all. It seems to happen most in the calendar, location of event field. Then theres the situation where the wordflow keyboard comes up, but swiping isnt working yet, if I start swiping right away it doesnt work. I have to stop, wait 2 seconds, then I can start swiping and it works fine. iPhone 5 on IOS 10.latest as of 5/15/2017
