Predictive text 'Learn from messages

[Barrsyboy1]

I have just purchased a S8 plus and I write a lot of generic emails and texts and my old note 4 would predict the next word I would say which made messaging much quicker. To do this I had to go into language and input, then predictive text, then go to personalisation and select 'Learn from Messages' but I can't find this option now on my new phone. Any ideas?
