The scheduled data refresh timeout in the Power BI Portal is limited to 120 minutes and for Power BI Premium users to five hours. Unfortunately, many of our customers have quite big datasets and as an incremental refresh is not available, many customers are facing the issue to refresh the whole dataset which in many cases requires more than 120 minutes and are hence running into a time out.
I suppose this is a big issue for many customers - therefore an increase of the refresh timeout to 240 or 480 minutes would be really appreciated!
