Plus-round icon not rendering?

I am building some icon buttons, all are working, but the plus-round icon isn’t rendering…
I tried, key for example which was fine, but for some reason, plus and plus-round aren’t rendering. Here is my code:

    <ion-icon name="plus-round"></ion-icon>

Not sure if it makes a difference, but I am using v2.

You probably want:

<ion-icon name="add-circle"></ion-icon>

Check here for icons that are available in v2:

Ahh, I was using the wrong docs, - I assumed v2.0 corresponded with the iconic version. Thanks for clearing this up.

Is it possible to create your own icons and then use them in the same way that ionicons are used, e.g. <ion-icon name="myIcon"></ion-icon>? Thanks.
