Xfinity Stream Beta on LG smart TV - Poor Quality

The Xfinity Stream beta app on my LG television was working great for months. For the past couple of weeks, the stream quality is extremely bad. It cuts in and out from HD to SD to very blurry. My internet connection is fine.

Troubleshooting steps: Rebooted gateway, DVR, and LG TV. Tested Xfinity Stream beta app from my iPad - it streams perfectly. Issue is just occurring on my LG TV app. The streaming quality affects both live TV and DVR recordings.

LG Xfinity Stream app version: 1.12.3

Any known issues or updates coming for the LG Xfinity Stream app?
