No predictive text in Scrivener

I have predictive text working on my iPad, but not in Scrivener for some reason.
Is there some small trick I’m missing?
I’ve included screenshots that show no predictive text in Scrivener but predictive text when trying to make this post, for example.

Check the setting at:
Settings App > Scrivener > Spelling & Substitutions > Auto-Correction

That’s done it.
I thought predictive and autocorrect were two different things.
Thanks very much.

I wish they were two different things. I can’t stand predictive text when writing (too disctracting for me personally), but I certainly need auto-correction when tapping at those little letters behind glass with my thumbs. I’d love to be able to auto-correct without predictive text, Would be great.
