When using word expansion, it's only useful for desktop users as they hover the word that the expansion is visible. But that's not the case when you're on a mobile device. Tapping the word that should be expanded is just not showing. So the feature only works on desktop which is a shame for all the mobile users who wanna know what the abbreviation is of a word.

Also in version 5 it's not easily visible that the word has en expansion. In v4 you had a dotted line under the word so you'd know you could hold your mouse on it to reveal the expansion, and the mouse cursor changed to a question mark but that's not the case anymore too in v5. (there is no styling for the abbr html element in v5)

A possible solution to make it work for mobile devices can be found here: https://bitsofco.de/making-abbr-work-for-touchscreen-keyboard-mouse/
Hope Invision will incorporate this in next release.
