How do you setup Account Preview

Open RBC Mobile on your iphone, then tap the 'more' (bottom right 3 lines on the screen), then 'settings' on the top right, then scroll down to 'features', select 'account preview', toggle on, and select accounts you're interested in. Go back to the 'settings' screen, select 'apple watch' at the bottom of 'features', and again toggle on 'account preview' and select the accounts you're interested in.

Having done this, I haven't got it to work yet, but hope it will when it finishes talking to itself. At least I'm sure it wouldn't work if I hadn't turned it on!
