I have mirrored my iPad to a Roku Device connected to my Android Sony TV. I can also cast my Windows 10 laptop computer to the Roku device. I don’t use it often but I tried both and it does work.
Mirroring isn’t the same. It’s slow to start up, requires faffing about with permissions, and you don’t want to tie up a device for sharing. Better to have the Wyze app in the various TV stores: Apple TV, Google TV, …
Mirroring to my TVs (Vizeo, Roku, Samsung) is a workaround but the whole point is to not have to use the phone at all, Would be nice to just use the TV remote to move around the screen.
