When I import a product file, I get the error "Something went wrong. Try again later". This has been an issue for over a month with no solution.

We're trying to implement a price increase for 4,000+ Product SKUs and QuickBooks Online is giving me the same error when I try to import a csv file. "Something went wrong. Try again later." Extremely frustrating when this has a huge financial impact on our company. I've been trying to import the files since mid-May and have no luck with contact from the customer service team.  Has there been any progress made on this issue?
