upgraded to 2.2.2.
   
   @andreychernih I think there are two different problems:
   
   1) The problem is related to the different logic of the scheduler before and 
after the update. Maybe there are no tasks in the running dags or something 
else. Can you show the rows for this dag run in dag, dag_run and task_instance?
   
   2) I agree with you that it is not the right behavior for the scheduler to 
continue scheduling runs that are earlier than the actual start date of the DAG 
or Task. It can happen, for example, after turning the dag off and back on. So 
I made a PR to fix it: https://github.com/apache/airflow/pull/21684
