On the main Agent Tickets page, if there is a long Ticket Status name, it forces the statuses off-screen to the left while in Portrait Mode on a mobile device. The statuses stay on-screen while in Landscape Mode. Tested on my own instance and the demo instance and was able to replicate the bug there.
