I have been receiving a shared control notification on all my same WiFi-connected devices from YouTube. When I clicked the notification, I found an unknown Android TV is being visible in Google Home under the Other Cast devices tab. Moreover, a TV box-like symbol is visible at the top of my android smartphone screen too. Upon landing on the cast device page, songs are playing with volume controls visible and are at my control. At the bottom, there are three options: 1. Add to a room, 2. Stop casting, 3 Open YouTube. Every time, songs/TV shows are played on the connected device. I don't have an Android TV in my home, however, I use YouTube Music on two of my devices.
Kindly suggest the best possible way to remove the problem. Is my device hacked? I run a security scan powered by Avast antivirus, it found nothing unusual. Is someone tracking my online activity? Or viewing my device screen?
