We have enhanced the fetch process with Cube. You can now re-fetch to single and multiple ranges, including ranges on other sheets, if the original fetch had an error.
From the Mini-Audit Trail. You can see all the fetches status and when a single or multi-fetch has failed in one click you can refetch the single or multiple ranges.
Select Mini Audit Trail button. This will show you all of the events from your add-on. In the event there was a failure you will see a red "x" for a single range and a triangle warning for a multi-range.
When you identify a single or multi range you'd like to retry select the circular arrow to re-start the fetch.
