Check the new
FAQ, where there is a link for updating your keyboard. It certainly isn't necessary on all phones, but would probably be an excellent upgrade on most Android 4.x devices.
Kukupecpec and I have already discussed this issue in messaging, but for the sake of posterity...
The 4.4.2 upload issue (also in the FAQ) will, unfortunately, not be fixed at this time. It might be addressed in a future release if I can find a suitable work-around, but I've already researched this numerous times. The problem is that in Android 4.4.2 Google switched to the Chromium webview, and for one reason or another they removed the FileChooser API. Patches for the OS should add the FileChooser API back in, but Google doesn't release patches directly to users, the provider (i.e. Verizon, ATT) is responsible for patching Android. The bottom line is that providers don't care about obsolete OS's, and focus on upcoming versions instead. [Please also be aware that security patches for your device are an issue the same as bug fixes like this--in fact a much larger issue].
The refresh issues will be remedied in the next update, which is basically already done.
