BlackBerry Priv autocorrect/Word Substitution problem

Dear community

Here in Switzerland we don't write german, we write swiss-german.
This means that the autocorrection from every phone can't be used � it "corrects" our slang.

My problem now is: I want to turn off the autocorrection but i still want to use the "Word Substitution" who was absolutely awesome on my BlackBerry Classic. (This is very lovely feature and it makes the live much easier.)
But I can�t use "Word Substitution" without active auto correct. I don't know why. It works very well on my Classic.

Is there a trick?

If you go to Settings->Language and Input->BlackBerry keyboard settings->Prediction and correction and turn Auto correction to off, the corrections stop on space correct?
If you then go into word substitution and add your chosen shortcuts to all languages does it work for you?

Yes, if I turn off Auto correction, the space correct stops.
It doesn�t work and I don�t know the reason why.

I got it. I have to turn on word suggestions.
Now it works.
