Hearthstone Updating Every Time

Everytime I start Battle.net, Hearthstone sits for a few minutes saying “updating” but I’m quite sure that it is not. I mean without fail it says updating everytime even when I know there wasn’t an update. Has anyone experienced this? Does anyone know why it’s happening or how to stop it? The game runs perfect and I have no issues, so this is a small issue, but I’d like to resolve it if possible.
