I am trying to upload around 200 ASINs through .csv file. It says your file will upload in 162 seconds and then nothing happens. Is there a template you have that shows exactly how it has to be set up in order to upload all the ASINs correctly?
Try to check the headers it must have the correct upper, lower case letters. (Product Name,ASIN,Marketplace ) must be separated in columns.
Otherwise, if it still won't work try limiting the ASINs up to 150 and then upload on a separate file the remainder of the 50 ASINs
What is the correct term for the U.S or .com marketplace?
It would be United States as shown on the drop-down menu.
