We have around 14,000 leads that we are trying to mas update. No matter if we select the whole list or by page the update never finishes loading on the browser.
So far we have been successful in updating some of the records, but we are having to piece meal everything. I have been successful updating about 200 leads by doing quantities of 20, 40, and 100 at a time. Is there something we need to do in order for all of the records to be updated at once with out doing small quantities?
