Hey guys. I'm new using Elementary OS and linux, I hope you can help me. The App center send me a notification about the updates, but usually, when the updates are finished you can close the app Center and it disappears from the dock. But some days ago, the updates are finished and I close the app center and it stays on the dock with the red dot of the notifications, but there's no notifications at all. Hope you can help me. Thank you all.
