I recently upgraded my Android phone. Mi 11 Ultra running Android 12.
I can no longer watch NowTV. I get the the error message, "Sorry we do not support HDMI streaming to your TV or screen recording on mobile devices..."
I am neither connected to a TV (I don't have one!) by HDMI, nor do I have any screen recorder running on my phone. No screen mirroring switched on either.
I've done all the usual. Uninstalled/reinstalled app. Cleared app data and cache. Turned off Bluetooth. Rebooted device. Checked to see if background apps are running. I even factory reset phone! Nothing has allowed me to use NOW.
Device is Xiaomi Mi 11 Ultra purchased in the UK running Android 12.
Sometimes there are background processes running that you can’t easily detect.
You might like to ask Xiaomi, or whoever supplied you the phone, if there is anything on there that might look like a streaming or screen capture process.
