Miracast problem with Roku Express

I set up a new Roku Express (model 3930RW) on 5/3/23 to turn my old TV into a smart TV. Airplay works flawlessly, so there is no problem with Wifi. Roku App on Android also works. Miracast (screen mirroring), however, refuses to work with all 3 Android devices (Android 8, 10 & 12) and a PC (Winows 10) I tried. Most of them can detect Roku Express but all fail to connect and the TV screen doesn't change or show any prompt. Some Miracast apps can't even detect Roku Express. I installed Airscreen app on one Android tablet so it can receive Miracast. The other 2 Android devices and the PC can mirror their screens to that Android tablet. So their Miracast software is OK. I have updated Roku Express, the PC and one Android device to the latest OSes (Roku version 11.5.0 build 4312-AE). I have tried Roku screen mirroring settings of Always allowed or Prompt, restarting Roku, rebooting the router, rebooting the senders and the result is the same.

Does anyone have success in mirroring their device's screen to Roku Express?

    While I don't specifically have an Express of any model, I have used Miracast without issue to my Ultra from a Windows laptop. Years ago I did have an Android phone, and I remember I had to have an app to enable screen sharing on my Ultra 4640 at that time. I don't know if that has changed with newer versions of the Android OS.

    For Windows, remember that the Miracast protocol requires the Windows PC to have a WiFi card, so a basic desktop PC will not be able to screen share to a Roku device. My Windows 10 laptop works just fine casting to my Ultra 4800. I recently received a Windows 11 laptop, and I have not tried screen sharing it to my Ultra. I'll try to remember to test it this evening.
