what about your duplicates? do you delete them? did you have to change the url in your settings back to your store url or did you keep the url for the google feed? if you are doing both?
I have found in the past when you are uploading and it asks you if you want to delete.....this causus the program to stop and get hung up.
so I do not delete at that point....and the GBSC only uploads what I have refreshed....and not the duplicates
example:
when I refreshed my catagories.....it said I had 1,000 items to upload....however...it only uploaded 500...which is correct...and failed the second 500 as duplicates
The weekly auto upload has worked 3 weeks in a row now....and I am going to keep it as is.
I can manually delete any duplicates or ended listings myself in the google base.
