The ClickUp to Todoist integration requires a "Ignore Tasks Older Than" configuration between 1 and 180 days to protect the limit of 300 active tasks per project in Todoist (and respect the GTD methodology). However, the logic seems to only look at the last modified date, which has the potential to ignore tasks with a due date long in the future. For example, if I create a task in January to renew my car's registration in October, this task will initially sync to Todoist then later be deleted long before the due date.

I believe this could be addressed by looking at both the last modified date and due date to create a sync window. This would still protect the Todoist active task limit while also respecting the GTD methodology.
