Bulk delete completed tasks
Currently there is no easy way to delete completed tasks other than having to delete each completed task manually one at a time. There is no Power Automate connector as well that enables deletion of completed tasks. Due this, for high volume Planner boards, keeping tasks per user within the limits is very tedious, time consuming. The inability to bulk delete completed tasks is posing a big constraint/challenge for Planner to be used when the number of tasks being created in high. A feature either in Planner and/or in Power Automate to be able to handle this more efficiently would be highly appreciated and useful.

When using the Planner app in Microsoft Teams, you can delete multiple tasks in "list view".
