The app is running so slow as to be useless. You. cant. type. anything. without. a. long. delay. between. keystrokes. Sometimes it takes minutes to get the IM app to allow typing. (this is on an iPhone 6s). And if you go to another app and come back, it loses its place and you have to wait for another few minutes to get its attention again. Its too bad, it would be a pretty great app if it performed better. And it makes me crazy when you click on "app support" in the App Store and it takes you to a website that has nothing to say about the app at all.
