Flow was stunningly inaccurate and suggestions/predictions were nowhere close to what I was trying for. Plus editing/correcting was slow making every message a chore. Supposedly this is better when logged in, but trying to log into a Microsoft account caused an error. Logged in with a Google account, but when trying to manage my data, the website was unresponsive. Nice ideas, but pretty unusable implementation. Sad to see Swiftkey has fallen so far since I was using it a decade ago.
