It seems users now face a difficulty to add new text replacement shortcuts in the latest iOS version. A click on the ‘save’ button to add new texts does nothing. Moreover, many users have reported all the previous additions are now missing!
For those who don’t know, ‘text replacement’ is a feature which can be activated from the keyboard settings where one can add shortcuts for commonly used texts.
This issue was first reported by users on reddit. It seems like there is no workaround available to the problem yet. So one has to put up with this annoying bug till the time it is fixed.
