[ionic 4] - how to scroll content?

Ionic Framework ionic-v3
1

I found the breaking change listed here: https://github.com/ionic-team/ionic/blob/master/angular/BREAKING.md#scroll

However adding scrollX="true" to ion-content still isn’t allowing scrolling (at least in chrome in device view - I haven’t tested on an actual device yet).

Question 1: Will this work on a device as-is?
Question 2: How can I make it work in chrome so I can test/build the UI?

Looks like scrolling is working fine in firefox, just not chrome.
While inconvenient I can work with it, will have to test on a device build before I sink too much time into it.

If anyone knows how to make it work well in chrome and/or anything else relevant please chime in.
