Can anyone tell me if it's common for youtube to remove ads from preexisting vids & stop placing ads on new vids even while the green $ monetized icon is next to the videos?? Why would they do this & how do I fix it..I've sent feedback etc & still no ads...I've uploaded new content that's ultra family friendly & still no ads. Is this considered being "blacklisted" so to speak? Any help in resolving this would be greatly appreciated...I've reached almost 4 million views & 5k subscribers since starting my channel 5 months ago & I'd hate to lose all that. Thx in advance for any reply.
