Thanks for the post.
It looks like your TV is still running the old OS. Have you tried checking for a manual update to see if you can update your TV to the latest OS 11.0? In addition, have you tried connecting your Roku TV to an alternate wireless network, such as a mobile hotspot, to see if you are experiencing the same issue?
For more information about how to check for a manual update, visit our Support page here: Update the software on your Roku
Please keep us posted what you find out and we will be able to assist you further.
Thanks,
