Thanks for the post.
It's possible that the issue you are experiencing is related to wireless connectivity as both of your Roku TVs are experiencing this issue. What kind of wireless router are you using and who is your ISP (internet service provider)? In addition, are you using a VPN for your wireless network?
With more detailed information, we will be able to assist you further.
Thanks,
