@TeamYouTube Thanks for your response. However, after several years, there is no reason for my impressions to go from over 4k to less than 200. I've checked my channel, I have no restrictions or anything like that. Something has gone badly wrong here.
@youtube I think your algorithm has gone to pot again. Or is this the normal rate of impressions for someone with over 500 subscribers after a day? A couple of weeks ago, my videos were all getting over 4k impressions.
