Hi @bmurphy1 ,
You could consider creating a Planner task and then periodically checking the completion of the task.
One Flow is used to create a Planner task, and another Flow is used to check the completion of a specified task.
The first Flow is used to create a task in the specified scenario and assign it to the specified user.
The second Flow uses Recurrence as the trigger, which periodically checks the completion of the task. If it is not completed, it can remind the relevant user. If it is already done, send a notification to everyone.
Best Regards,
