When I create a document using OpenXML, and use Subtotal, Aggregate or {} array formulas, they are not calculated when the user opens them. This is a WebAPI application, file is generated on server.
If the user selects each cell and presses F2 and then Enter, the formula is calculated. For the pure array formulas they have to go to the formula bar and press Ctl + Shift + Enter.
This is, of course, completely useless. The problem does not occur with Excel 2016 (I don't have a copy of 2013 to test).
Any thoughts on this?
