I have a workbook with a custom SQL data source with a live connection on Tableau Online. I've noticed that when I refresh the view, it doesn't always show the most up-to-date data. When I run the same SQL query in MS SQL Server, I see different data. It takes about 20-30 minutes for Tableau Online to reflect the same data. If I go into Edit and refresh the data source, it shows the most up-to-date data, but with the refresh in the View, it does not. How can I make refreshing the View show the most up-to-date data?
