For future dividends, you would have to go to settings and select “Display Cash Balance” checkbox.
Tip: You might also want to select “Add unpaid dividends to Total Assets” checkbox if you like unpaid dividends (i.e. ExDate has passed but PayDate is yet to come) to be considered as your total assets.
For past dividends, you would have to go here and click on “Populate Cash Balance Dividend” on the top right corner. This will re-compute all the dividends you were entitled to based on your transactions.
