WARNING - Do Not Update Your Adam!
There is a problem with the update. The whole update file is not being downloaded. Notion Ink is working on the problem and will have it resolved soon. But for now, be sure to postpone your update. You will be receiving an official email from Notion Ink soon stating the same.
So fanboys, lets see how you will get out of this one, with out acknowledging that Rohan and NI, actually are able to make mistakes! !
