Re: Airplay and casting video don't work on Roku Express 4k+ 3941x running 10.5.0
I have the exact same problem with no pictures being displayed on screen mirroring from iphone running version 15x on roku 10.0. Both ONN and TCL TV's and the Roku stick. Roku tried to pass me on to the hardware manufacturers when clearly this is an IOS 15 issue with Roku software. Please fix. Used to work great. Was going to invest in Roku, but now from what I am seeing, the deal is off.
Re: Cannot find Roku Express 4K for screen mirroring on any device.
I've tried everything on mine also and I finally run across an article from Roku that said that you have to have a Roku tv like the 3900, ect. for it to work. It took awhile to find out what was going on, they don't make it to easy to find out info. I even seen that the Roku people are not versed on all the products they sell, which is kinda crazy. But oh well.🤪
The "3900" was Roku Support explaining that mirroring is generally supported on all their newer devices (streaming players and RokuTVs), but was clarifying that regarding the older Roku Express devices, mirroring is supported on Express models 3900, 3910, 3930, and 3931 but not Express models 3700 and 3710.
Hope that helps clears up the confusion.

I think I figured out why this is happening...It appears to be an ios 15 upgrade issue. I have the same problem with IOS 15 on three Roku Devices....tcl , onn and Roku stick. They all work great with an iphone on IOS 14, with IOS 15, music mirroring works, but if you try to show any pictures on mirroring, its a blank screen. Please fix. Thanks.
Looks like IOS 15.1 update did the trick. Screen mirroring is working now! Hard to tell whether it was an Apple or Roku issue but appears to have been an Apple issue. Can now mirror photos, etc as before.
