Re: Wrong date for Planner Task
1. For understanding, the posts you had read were most likely using "today's date" and converting it to their local time zone. In those cases, they are using a function called utcNow() to grab today's date/time, but that would be provided in UTC time and if you needed the exact time you would convert it to your local time zone.
2. As for providing the results...there are a couple of ways to do this.
a. In the top right hand corner of your Edit screen, you will see a "Test" link.

Click that and trigger your flow...(if you are running this manually, just start it up). Once the flow has completed, just open up that compose statement you created and it will show the results.
b. Trigger your flow normally. If you click on the flow (not edit), you'll see a screen with all the Flow properties. At the bottom, you'll see a 28-day run history. You can click the last flow you ran and you can see all the results of the flow. Open up the Compose statement and paste in the results.
