I bought a Mi Box 4K around a couple months back and a few days ago, it received a system update. Since then, I am not able to cast any of my android devices or even the laptop onto it. It's connected to the same WiFi as my other devices. I tried uninstalling the updates of the Chromecast service app and updating it again, clearing its cache and data, force stopping it, even reset my Mi Box. But it still doesn't show up when I select cast on my phone. Even the cast icon doesn't show up when I'm playing a video on YouTube on my phone. I even tried using the Google Home app and it doesn't show the Mi Box when I'm trying to add a new device.
It is running Android TV version 9 and the Build says PI.2696 release-keys.
How can I solve this?
Thanks!
