I was among those who could not wait for Apple to open up iOS 8 to third-party developers. One of the main reasons was so I could use a different keyboard.
Which worked great…for a while. Now I’m running into a problem where no keyboard pops up at all when I have a third-party keyboard set as the default.
I notice it most often when I’m doing a spotlight search.
To fix, it I have to leave spotlight search, open up a note, and pray the keyboard pops up so I can switch to the default keyboard (Tap the globe button on the keyboard to toggle installed keyboards).
Now I am reconsidering using a third-party keyboard at all.
