I was trying to chromecast my screen on my android tv through Google home app but it was not working properly, i checked my wifi and there was no problem with it, I clear cache of my phone and restarted it and also reset my tv and reinstalled google home app on my Redmi note 9s and updated chromecast on Android tv but nothing else smae happened! An idea emerged to check whether it is happening with other phones or problem with note 9s, I casted my mobile screens of Redmi note 9 and realme 3 devices and it worked fine that's mean it is problem with note 9s only!
