Has anyone else had issues with app updates failing in the new Market? I can't remember ever having an app fail to update, until the new version of the Market came to my phone. I just performed updates on 15 apps, and 6 of them said "failed to update"... and it says "Unknown reason - 18" Tried rebooting the phone, and trying the updates again, same thing. All the others updated fine with no hassles. Anyone else?
