Getting this QuickBooks Online error when editing quotes: "Error while calculating tax." Often have to recreate the entire quote to send it. Huge time waste.

Is anyone else experiencing this error in QuickBooks Online when editing quotes/estimates? Error message: "We're sorry, QuickBooks encountered an error while calculating tax. Try reselecting the tax rate or reentering the product/service item and saving the form again." This happens while editing existing quotes. The suggested fix rarely works, and I often end up having to recreate the entire quote from scratch just to send it to the customer. It's becoming a major issue as it's wasting a huge amount of time. Has anyone found a permanent fix or identified what causes it? I'm using QuickBooks Online in Ireland with VAT enabled. Any advice would be greatly appreciated.
