It's clearly a bug/glitch with YouTube, but they refuse to admit it. I have a topic here, and I'm reaching out to my community to get my problem resolved:
If anybody has seen an overlay ad in the past 7 weeks on any of my videos, let me know and/or take a screenshot. Overlays are the small banner ads at the bottom of the video.
Guys, I need your help on this, or I may have to give up producing Unity tutorials.
As a reward for anybody who successfully helps me out, I give to you a free project file.
