For nowI've disabled pihole, then opened an incognito Chrome window (with no ad blockers), and haven't seen a single advertisement on your channel (either in the form of video ads at the start of the video, or a banner text ad overlaid on top of the video, or when skipping to different timelines in the video that trigger video ads). I tested about 10 random videos from the channel.
Just to confirm that it wasn't a fluke, I looked at other youtube channels, and I got flooded with ads.
Then, I repeated the experiment with an incognito Firefox, and same thing...no ads for your channel, but ads for all other channels.
Then, I repeated the experiment with an incognito Edge, and same thing...no ads for your channel, but ads for all other channels.
Then, I repeated the experiment with my iPhone, I simply enabled incognito mode for Youtube app, and same thing...no ads for your channel, but ads for all other channels.
So...everything looks normal.
In my experience, the higher the views the greater the chance they attach ads.
Amirs channel is still new. Just wait
