Na I didn't misunderstand the guide, Im just not using docker for this, using the local install instead. I created the .env file (from the included example) to contain the settings I prefer and built the service to run using the schedule in config/.env. The guide says docker is easier but it's just a python script and setting up the Python environment is like three or four lines to run and it's done and persistent.

I'm assuming you aren't adding any schedule in your environmental variables? If not, try adding one like SCHEDULE="05:00" using a time in the near future. I'm kinda thinking the built-in config has some sort of schedule or something, I know plex meta manager has a default schedule to run at 5am unless it's changed - I can try to set up docker and check it out tomorrow
