I just tried checking my User Dictionary on my 2 main phones, & I always end up immediately exiting the Kii settings screen & entering the Android main settings screen. I didn't use to have this problem. & I don't have this problem with the Texts shortcuts even now, although it must have far fewer entries than the former.
I don't have this problem at all with my 2 backup phones. Of course they are fresh installs & only have 1 user dictionary entry. I tried backing up & restoring settings from 1 main phone to a backup phone, & I can still see User Dictionary, but with only 1 entry. The other entries were not copied. The text shortcuts were copied though.
O, I just tried using some expected user dictionary entries, & they are recognized, even if they don't appear in the list! What gives?
This might be related: when I click on Languages & Dictionaries on the Kii Quick Setting screen, 50% of the time, I sometimes end up back in the previous app, ie. messaging or calendar, instead of in the Kii settings page.
