Every time I try to upload my edited CSV to get the new materials in on my literally hundreds of products, the processing indicator pops up, stays there for a minute or two, then vanishes. There's no preview, no error message, and no changes to my materials. Is this an indication there's something wrong with my CSV or is this just the system mucking up during processing like it does with file uploads and preview renders? I'm using Chrome, btw. Black Acrylate was a big part of my sales and I need to get the new professional plastic/HP material up to mitigate at least some of the damage.
