App Restarting: Fox News on Roku Devices

This issue is definitely NOT solved. I experience many of the same symptoms other users reported in this thread. I had this issue for more than issue on two of my Roku 3 Ultra devices. I finally decided to upgrade both devices to Roku 4 Ultras thinking it would surely resolve the issue, but unfortunately the issue persists where I have to physically unplug or manually soft reboot my Roku device before launching Fox News app for it to work. Then, after watching for a period of time (sometimes within 15 minutes, sometimes after an hour, it will suddenly display the Fox News splash screen and the spinning circle (it used to be 13% with the Roku 3 Ultras, but now it usually shows 33% loading on both Roku 4 Ultras). The point is, this is obviously a problem specific to this app. I do not have this problem with any other app, nor have I ever had this problem with apps for all the many years I've owned Roku devices (since the first version of Roku).
