Keyboard shortcut expansions not being expanded I have defined several keywords on my iPad Air 2 (iOS 8.3) in order to let iOS expand them when I type one of these keywords.

However, these keywords do not expand. How can I force my iPad to expand them?
Some apps do not support iOS keyboard shortcuts, having disabled autocomplete. Try using a first-party iOS app and see if the shortcuts work.
Make sure you have defined the shortcuts in the right way, whereby the "Replace" is what you type and the "With" is what the autocomplete should fill, not the other way round.
