The package mox-support was missing for a while, but right now, it is there. If you received this notification, you shouldn’t receive another one. Updater is running each 4 hours, so if you got this notification, you close it. You can check it if you go to the Updater tab and click on the button “Save and update”. It will run Updater on the background.
We are sorry for any inconvenience caused by this.
