Good point @William_Larsten! I tried adding this as a condition to the view so the filter formula looks like this:
Created(thisRow)>=[15 Seconds Ago]&&Item.IsBlank()
The issue is that the Item.IsBlank() condition still filters out the row immediately after you enter in the data. The reason why I like this condition is because if the user accidentally clicks in the view but decides not to add any data, this action will create an empty row in the master table. Empty rows in the master table doesn’t appear to affect counts or sums but just clutters the master table with empty rows. I suppose the tradeoff would be an uncluttered master table (but with immediate filtering for the user upon entering data) vs. a nice delay for the user as they enter data with the possibility of a cluttered master table.
