There's a 30 second timeout for the loading screen in our dataset. If after 30 seconds, there is no new data, the grid will switch to show 'No data available'. If the request is still running in the background, and it completes after that, the new data will be loaded in. Please increase the timeout for the loading screen in our dataset to 40 seconds to 1 minutes so that the user will not get confused with the behavior.
