Cannot type accents by holding in certain apps
Macs have a function wherein you can hold a letter and it'll display various accents which you can then use. I love this feature, but it isn't working in certain apps; it works just fine on chrome and textedit for example, but doesn't work in safari and pages. Mainly the latter is a serious issue since I use accents quite a lot, so not being able to use this feature is a bit dissapointing. Does anyone know how I could fix this?
P.S. I am aware that it is possible to type certain accents using alt+e, alt+u, etc, but this is not what I want.
