FAQ
Because access to the additional dictionary is restricted depending on the OS version, we have changed the storage location of the dictionary file from Lab-256 released in September 2020.
If you would like to continue using the additional dictionary, create a new "wnnlab" folder under internal storage/android/data/jp.co.omronsoft.wnnlab/files/ and move all existing dictionary files under /sdcard/wnnlab/.
After moving the files, the dictionary files will also be deleted if you uninstall Wnn Keyboard Lab. Please make sure to keep a copy of the dictionary files separately in advance.
