I can't get any third-party keyboards to work on my iPad Mini Retina. They always glitch out. I've tried adding and removing them from settings, reinstalling them from the App Store, and rebooting my device several times. No matter what I've done they don't work. For instance, Flesky is just blank. SwiftKey shows a blank keyboard frame. There is no way to switch between keyboards unless I use them one at a time using settings, and I have to remove them all to get the default keyboard back. Has anyone found a way around this problem?
