I am VERY new to PowerApps. It looks like a very useful tool. I am creating my first one with a basic app from a sharepoint list. Everything seems fine but I am not able to sort the gallery by a completed date in descending order. Here is the formula I am using.
Sort('TableName', "Date Completed", SortOrder.Descending)
No matter what I do it will not sort by the Column "Date Completed" in a descending order. The advanced section under the data portion to the right has a yellow triangle at the bottom of it too. I am assuming something is wrong but not sure what it is.
