Let me state up front that I am not an Apple guy. My wife has a current iPad Mini 5 that includes Airplay but that's the only Apple device we have in the whole house.
I have two Rokus on 9.4 that include Airplay capabilities. I have Airplay turned on on both Rokus. I could swear when this first came out I experimented and got my Streaming Stick+ to stream from the iPad via Airplay, but now when we click the Airplay icon while viewing a video on the iPad, the only device shown in the iPad Airplay popup on the iPad is the iPad itself. iPad and my Rokus are connected to the same local net, and the Roku app on my phone connected to the same net sees all of my Rokus.
Where do I go from here?
