Hi. I have a Prefect 1.0 flow using ECSRun Task. It as originally registered with a memory value of 2GB and created successfully in ECS. Later, we changed the memory to another value and re-registered, but the Task Definition is not changed. Is there anything obvious that we might be missing?

you're right, there is an open issue for it https://github.com/PrefectHQ/prefect/issues/5550
