More specific information on negative keyword conflicts
When a negative keyword conflict occurs in an account, Bing could provide the negative keyword list and the specific keyword that is triggering the conflict. This would save time required to search each list and filter for possible keywords causing the conflict.
You can go to the Keywords tab and filter by Delivery Status = Negative Keyword Conflict. See list of delivery statuses here – https://help.bingads.microsoft.com/#apex/3/en/hlp_ba_conc_editorialstatus.htm/1/en-us/#ext:keyword_load
