The dotenv module should be prioritizing my .env.local file over my .env file, but it's not. When I have REACT_APP_API_BASE set in both files, the app always uses the value in .env. It only uses the value in .env.local if I delete the matching definition in .env.
.env
REACT_APP_API_BASE = 'https://api-staging.mysite.com/api'
.env.local
REACT_APP_API_BASE = 'https://api-qa.mysite.com/api'
The app is making API calls to https://api-staging.mysite.com/api/endpoint.
What am I doing wrong?
For reference, I'm not running react-scripts directly, I'm using CRACO.

Five minutes after posting a bounty, I finally figure it out...
One of my files had require('dotenv').config(); at the top. Apparently, this was overwriting the configuration found by CRA with whatever was in the main .env file. Once I deleted that line from my code, everything worked fine.
