Can't Access Data API in Live Mode

I can access the data api on my app using version-test (404 response), but not version-live. When I look at ‘Settings | API’ in live mode I see that:

  • ‘this app exposes a data api’ is not checked, although it is in dev mode.
  • checking it has no effect, and setting it does not persist when going to dev mode and back to live
  • I cannot generate an api token in live mode
