Can you please suggest how can we achieve this scenario without code
when a record is not approved for 24 hrs ,change approver related to the record to delegated approver from the actual approver

Hi, we have a number of tasks that are automatically added to opportunities using Process Builder and Flow to pass different assigned too and due dates etc.  What I need to do is if an opportunity is marked as Stage = "Archived" i need a flow to check if there are any open tasks on the opportunity and then delete them,

We need to delete rather than close as these tasks are asociated to steps in the closing process and if the opportunity is archived the closing process stops so I dont want these tasks to show up for my users.

How do i use a flow to check and list all tasks that are open and then conduct a delete action?
