Docker(?) not picking up changes to local files

I’m having a problem where my PHP code is being cached on the server side, so when I’m running devilbox, even after I make a change to the code, I can’t see the change unless I stop and restart devilbox. Obviously this is a very tedious process… !

At first I thought this might be a server issue with caching in nginx or something… but when I manually go into the Devilbox shell, I can see that even though I’m changing my local disk files, they don’t seem to be getting into the Docker container. From within the shell I don’t see my changes. Ugh.

How can I fix this?

I’m on a Mac and here’s my Docker Desktop – I think it’s the latest version of everything.
