All of the below devices (screenshots) are connected on a mixed mode 2.4GHz/5GHz single SSID wireless network on the same subnet. The iPhone and the MacBook can successfully AirPlay to the RokuStick, but not the RokuTV. Outside of these four devices all being specifically connected over 5GHz, I also have iPads that connect via 2.4GHz and can AirPlay Zoom meetings from the iPads to the RokuStick just fine.
While your "solution" and proclamation to mark the thread as solved and fixing what all of the commenters and Support staff haven't solved per the comments from the previous 8 pages of this thread over the last 9 months, I can 100% say it has nothing to do with either 5GHz or 2.4GHz wireless connectivity, but congrats on solving your own problem.
