I have a Fly app deployed in ewr that manages other Fly apps in the same organization.
I’ve noticed that running fly logs -a ${APP_NAME} on my local machine gives me the log output for all regions. However, running the same exact command on the Fly app only gives the output for a single region (ewr in this case).
Local output:

What is causing the output to be different when it’s the same exact command that’s executing?
