I have been using IMPORTRANGE and QUERY extensively to connect all of my spreadsheets for a while now. But recently noticed that IMPORTRANGE and QUERY will not return proper data unless the source Sheet is open. Also, the data used to automatically update (every 30 min or so, whatever the default refresh rate is) in the background for IMPORTRANGE, but now it will only update if I manually open the Sheet and it will display "Loading...." before returning the data.
Is anybody else having issues with these two functions?
