I have a laptop running windows 10. The Tv is a Mi Tv 4a Pro. Earlier it used to cast seamlessly. But after I installed the software update on the TV (currently running 9 and no further updates to show), my laptop is unable to detect the TV. Casting from phone works fine. It has chromecast built in and also has miracast (although miracast disconnects the Tv from the wifi idk why). Any help would be appreciated. Also if there’s a way to mirror an iPad Air 3, kindly drop in some how to link or steps.
