PC I've Bought West Cornwall Local On Epic Games But It's Not Showing Up

I purchased West Cornwall Local on the Epic Game store on Thursday night and it is still yet to show up in my playable routes. I have tried:

1. Uninstalling and reinstalling the content
2. Running TSW from the launcher in the folder rather than through EPIC
3. Waiting 3 days to see if it shows up.

Please advise on how I'm supposed to access the content I've paid for.
