Hi @Anonymous ,
Please share your flow configuration or requrements so we can get the clear idea.
I got the Idea of your Microsoft Flow Solution,
Procedure
1. Recurrence.
2. When a new task is created trigger for Planner.
3. further Actions as per your requirements.
Here i just want to add one thing that the Trigger checks for the new Task Creation only after the Recurrence trigger runs.
for Example, if You have set Everyday value in the recurrence Trigger,
Then Today's Tasks can be Fetched into Flow Tomorrow because todays Tasks are Created at the Day time. not at the Time of Flow run.
hope it would help you! still if you have any queries feel free to post here.
Thanks,
Dev_Nikhil
