C:\Users\v-jormc\Source\Repos\Responder\responder.pwa>yarn start

I think it may be because I am on Windows. Trying to find another option.

Yeah it's related to this bit of your script: PORT=3001 yarn start. It's not related to concurrently proper.

Created an .env file facebook/create-react-app#1083 and moved PORT to there and seems to be working now

Change to "start": "react-scripts start", it work for me
