Below is screenshot of a refresh schedule someone set. looks like there is a limit of 8? Is there a way to change this to every hour? The base DB that is being refreshed is from AWS.
Unfortunately, you only have 8 scheduled refreshes a day. If you have a Power BI Premium Subscription they allow more scheduled refreshes, but not many companies or individuals that have that subscription due to the price. Think it starts around $6k a month. You can push as many manual refreshes as you wish, but only 8 can be set through schedule refresh.
