Django static files not updating inside docker container - django

Question

My Django project uses Docker, gunicorn, and whitenoise. I recently altered settings to prepare for deployment, most notably adding configurations for AWS-hosted media files. Now when I run the project locally and collectstatic the static files do not update in the browser. I do, however, see the changes where static files are collected.
Things I've tried/double checked:
Ensuring I have a shared volume between the container and where static files are kept/updated
Adding a step to collectstatic in my Dockerfile
Confirming my static files settings
Is something about django-storages causing the issue? I thought that previously I was able to make SCSS changes and have them show up by refreshing the browser. But that's not happening. Even running collectstatic inside the container has no effect.

SOLVED
It turns out there was a duplicate, stale file with the same name, and the same path. The template was looking for /static/pages/scss/styles.css, which existed in its updated form in my root static directory, the correct spot. But there was also a file in pages/static/pages/scss/styles.css that must've gotten generated during previous changes to settings.py. Somehow I guess that file was getting repeatedly pulled in and overwriting the updated version. All was fixed once I deleted the stale file.
