We had the same thing -- items approved but just *one* color was disapproved (Is Coral Pink a violation?). I think the issue, for us is the word Tactical. We offer 275 Tactical Cord -- could the "T" word be a flag? But if so, why just Coral Pink? I've not received an answer to that as of yet -- will report back if I do...
We also had quite a few items noted as "not searchable". So I used this form asking what was up:
and selected: Please send me an email detailing my feed's errors and instructions on how to fix them
Is this where you made your request? I received an personalized response over night that everything was fine with screenshots (had to follow up on the Coral Pink this morning) -- and the not searchables are searchable today.
