Hello Taha, thanks for letting us know about this.
When I view the column for "23 September Traffic", I see traffic data for ~50 cells, and a handful where we see "Traffic Not Found".
Could you let me know a few specific domains where you got data within SEMRush, but see "Traffic Not Found" within Clay? Or were you seeing this for every single one you checked?
I'd like to make sure I'm looking at the same ones you're concerned with.
