Contacts not popping up when composing Gmail

[LandLockedPH]

I've notice that when I start typing a contact name, it doesn't pop up in Gmail and autofill the rest. This works find in other email applications and in Gmail on other Android devices. It does not work on my S7E.

Any ideas?

I finally uninstalled Gmail (taking it back to original version) and then updated it. When I next went to compose an email, I was asked if I wanted to allow suggestions. Which of course, I said yes. Works perfectly now. I don't know how that option got unselected.
