Alright, so maybe I am getting old, but I recall in iOS 10, and I was pretty sure in iOS 11 too, but when the onscreen keyboard pops up, if you perform a long press on a letter, or even on an emogy, you typically get access to special characters. For example, for French users, if you wanted to type in a "É" or "à", you would simply long press on the "e" or "a" and a list of special characters would pop up. I also believe that this was the same action to access alternative versions of an emogy.
For some odd reason now, when I do the long press, nothing pops up anymore. Now either I am going mad or something has changed on my phone. I do recall being able to access these alternative characters when I first got my 8 Plus, and at the time, it was running iOS 11.0.1, but the only change I had recently was the iOS 11.0.3 update a while ago.
Has anyone out there also encountered this or even know how to fix it? Would appreciate any assistance. Thanks!
