Hi @doitdude,
Thanks for raising this concern directly to us, and welcome to the Roku Community!
We will be more than delighted to assist you further with this issue that you have had with screen mirroring since it stopped working. Most of the time, your Roku screen mirroring starts working by only reconnecting the devices. Disabling and again enabling the Wi-Fi on your devices may resolve your issue. If you still fail to mirror, then set your TV screen mirroring mode to “Prompt.”
Please try doing this and see if it helps with what you're experiencing.
Best regards,
John
