Hi @G, Charlotte,
As per my knowledge, it is by design in Excel for online/web. As an alternative, we use copy and paste instead to link date/cells. See this: Create an external reference (link) to a cell range in another workbook. As it is by design, we don't have a workaround for this. It is recommended to provide feedback to let Microsoft know your requirement via Excel desktop application >> File >> Feedback.
