I wonder if it was my guest video, cause everything I though turns to yellow at the minute
My last 3 proper videos (not live streams) have been demonetized, I only had enough views on one of them to get it properly reviewed, but the other two also automagically fixed themselves after a day or two.
I released 20+ videos last year and none were demonetized (although a lot of them weren't monetized at all to begin with)
It doesn't really impact me at all but at the same time it's very frustrating to not have a clue why it's happening.
