We have a managed Airflow instance in our subscription, and the UI shows that the last heartbeat was a day ago (08/09). I tried resetting the Airflow instance multiple times, either by changing a variable or importing dags from a storage, and nothing worked. I also tried looking at logs, which yielded no results as well.
Help? I have no idea what to do next or how to fix this problem. Thanks.

If there were any recent package installations, such as
apache-airflow-providers, try uninstalling them, as they might be incompatible with the Airflow version managed by Azure.I tried to reach you offline but you were not available. Since the Airflow scheduler heartbeat has been missing for more than a day and restarts haven’t resolved it, this indicates a possible backend service issue that cannot be fixed from the UI or configuration changes alone. I’ll reach out to the internal team to investigate this further for your Managed Airflow instance and will update you once I have more details.
