From 12:02 PM PT to 2:22 PM, apps that checked for new updates from EAS Update and had a new update available would not launch due to a parsing error.
Apps were affected if they were not running in the background and had a new update available. Apps that were running in the background or already had the latest update or for which there was no update were not affected.
