@TeamYouTube I am having an issue on my newest video, which has been switching between Green and Yellow demonetized symbols for the past 5 minutes. It started green, then went to demonetized, and then back to green, and finally now yellow again. The vid is totally ad friendly..
It helps if you clear your watch history every now and then. You'll be surprised how many videos you missed over the past few days start popping up.
