I signed in once shortly after hiting 120 and the gear on my page is way above the items listed. I can seem to find a way to update armory link.
You can click on your character name at the top of the page and import from the armory there. I am not sure if the armory API is updating right away or not. If the iLevels don’t look right, try importing from our addon. If they still don’t look right, let us know because it means we have to fix something.
