Hi @JamesFiiO - please can your engineers look into the issue with lip sync and YouTube videos. I’m watching YouTube with Chrome and with the Vanced app, and in both cases the video appears slightly ahead of the sound. It’s very slight but it’s there. No sync issues with Netflix or Plex videos. I’ve also installed the Roku Mobile app, and watching anything on the TV with the audio coming through the app on the M11 results in slight lip sync issues. Hopefully you can find a fix, or add some sort of lip sync adjustment option or audio delay/speed up to the Audio Settings options.
