YouTube ads never show no matter what the player style or what the video.
Actual YouTube version: 10.18.55 YouTube Android Player API: 1.2.1
I remember that I saw some ads while was developing my app. Now I can't see any ad after hundreds of tests. This is actually a problem, because my app gets constantly suspended or rejected because of "unauthorized use" of YouTube API. Google Play Support Team thinks that I disable the ads somehow. Please confirm the issue.
CHROMELESSas thePlayerStyle? If so, try using the default one. In addition, what device are you testing this on? - Sebastiano
