I currently have Android 4.1.2 on my galaxy s3 from Verizon and I am having issues with the notification bar. Seemingly at random it changes how the notification bar works. I had recently updated the gmail app to allow messages to be archived from the notification bar. However later the bar changed back to the old style where it no longer showed snippets of the email in the notification bar and I can no longer take actions for new email. At the same time I noticed new notifications are tacked on to the right side of the list instead of the left side when the new features where working.
Has anyone else experienced this issue or figured out a solution for it?
