Numbers STOCKH function errors out for mutual fund and ETF prices

They appear to be correcting the issue, slowly. Many of my price histories for that date are now being populated with actual prices, but, for me, VTI still errors out. Try it with "JMUB" and see if it gives you an error like it does for me still. Could be a caching thing. Yahoo Finance (which is Apple Numbers' source data) had the same issue but fixed it within 24 hours.

You are not using the date "08/28/2026" which produces the error "Data for the ‘close’ attribute isn’t available for the selected symbol."

The same error occurs for any Mutual fund or ETF price history inquiry for August 28
