Premier Developer consultant Brian Gregor has launched a new series on his blog called PowerAppsPuzzle where he shows examples of issues and solutions in PowerApps.  Here’s an excerpt of the first puzzle in the series:

Let’s take the scenario where you have a ListBox in a PowerApp that contains sorted information – either alphabetically or numerically, doesn’t matter – similar to the following:

The user selects 1, then 2, then 4, and all is good, however you may notice that sometimes the values are not sorted. You may receive the values out of order like: 4,2,1 or 2,4,1.

Check out Brian’s blog here for the solution.
