   Hi all,
   What's the current status of this issue? It seems as we are facing exactly this behavior. I will shortly try to explain our use case:
   We have a daily job to import new data and the last task of this job is to clear the dags from the previous 30 days to check if some data from the previous days has changed. And instead of processing day by day (as I would expected because of max_active_run=1) the tasks are scheduled randomly across all days. Unfortunately, I can't share the full DAG description but the image bellow shows the behavior pretty good:

   Thank you for investigating into this!
