As of January 2023 the manual importing of a QBO file no longer works. I tried both the December 2022 and January 2023 QBO files for my Apple Card statements and QuickBooks just hangs and has to be forced to stop. After 20 years of being a QuickBooks user about to migrate away to another product as I am tired of these types of issues (notwithstanding that this should have been an automated process by now) especially giving the pending move to annual subscriptions only. WTF Intuit.
