Hi @lawnmore,
Welcome to the Roku Community!
Thanks for bringing this to our attention, and rest assured that we have taken note of this. Additionally, we'd like to know more about this issue so we can look at how we can assist directly. What specific issue are you having? Also, have you tried performing a system restart on your Roku Ultra device using its remote? If not, then we recommend doing so by navigating to Settings > System > Power (skip if no sub-menu) > System Restart. After this, kindly check to see if you notice any improvements.
Let us know, and keep us posted.
All the best,
Kash
