[4.5.0.16] predictive text input broken

REPRODUCIBILITY: unsure
OS VERSION: 4.5.0.16/4.5.018 (licensed version)
HARDWARE: Xperia Xa2
UI LANGUAGE: English US
REGRESSION: predictive text input fails

DESCRIPTION:

When typing on the keyboard no “word suggestion” is provided. The clipboard icon appears, the rest of the line is empty.

PRECONDITIONS:

During upgrade I was recommended to remove a few packages related to predictive text input (not sure of their exact names). I uninstalled them using pkcon remove. The upgrade went well but after reboot I had lost predictive text input.

After refreshing the package list (pkcon refresh) I tried to install it Jolla store but it simply says “waiting” to end up with an error.

Predictive text input worked well before upgrade.

STEPS TO REPRODUCE:

  1. system upgrade to 4.5.0.16 (upgrade to 18 did not fix or change anything)

EXPECTED RESULT:

Working predictive text input, ie word suggestion as you type or Chinese characters displayed as Pinyin is input.

ACTUAL RESULT:

empty row at the top of the keyboard (only the clipboard icon shows up)

MODIFICATIONS:

No change applied, simply followed to recommendation to uninstall xt9 related packages.

ADDITIONAL INFORMATION:

Among the other things i tried:

  • enable/disable different languages
  • uninstall/reinstall jolla-keyboard-layout-chinese package
  • restart maliit-server
  • reboot
