Can't drag and drop items in spreadsheet?

I am tearing my hair out here-- I am unable to drag and drop items in my spreadsheet. I can drag an item to be a subcategory of an existing item, but the described behavior-- drag an item BETWEEN two items, and when the blue line appears drop it and it will be between the two items never happens. Either I get a blue box that surround the whole spreadsheet and the item stays in place, or I get a blue box around an item and the item I’m trying to move will become a subcategory. I feel very dimwitted. What am I doing wrong? :confounded:

Just to check, you haven’t reordered your spreadsheet by a column other than the chronological order (the # sign column)? Once the spreadsheet is reordered by something other than this, you can’t reorder it by drag and drop. However there should be a message appearing when you try to drag and drop that says “Sort by # to allow row-reordering”. Does this happen for you at all?

I’m having the same problem.
