We have been having a hell of a time trying to get the multi-inventory + export plugins to function properly together. We have over 10k products on our site and wanted to add multiple inventories for each item. After fighting with the export function of the PRO Export plugin for a good long while we finally got the required CSV format and ID information to perform an import. Now when we attempt to import our product listings with updated stock levels it says the "Subentity product is not importable. All its subentities won't be imported either." Which is very frustrating because we are using the exact same template and info that was exported from this same system. After roughly 400 products scroll past on the importer, the entire process stops and just sits there forever. Please let me know what we are doing wrong and how to correct this issue. We have tried to reinstall the ATUM plugins, disable other plugins etc etc to no avail.
