What I want you to do right now:
Open your YouTube Studio.
Pull data from August 10 to today.
Segment by device.
Screenshot the desktop dip.
Then tell me in the comments what you see.
This taught me something crucial:
Analytics gaps happen outside your control.
Filter lists update.
Browsers change.
Tracking breaks.
Your job is to SPOT it fast and explain it clearly.
If this helped you think through the Dec 16 shift, let me know in the comments.
And if you're planning tests before launch, I want to hear what you're prioritizing.
