I already choose to "Let user choose to display the alert or not" in the Startup Prompt, but every time I open the workbook, there is no startup prompt to let me choose whether to update links to other workbooks.

I need to manually click Update Values myself for all the sources, then my workbook will be updated with information from other workbooks.

The startup prompt was there before, but now it was gone and I do not know how to get it back.
