Native and M2M connected to the same database behave differently

Hey I am running a M2M application against a backend server. On the M2M application everything works like authorization. Getting data from the API. Now a tried to add a Native application to it. React native with webauth module. Using the client_id I managed to get a accessToken and a idToken. Using this accessToken I make a request to the API and get:

{
  "timestamp": "2019-04-11T10:57:42.921+0000",
  "status": 401,
  "error": "Unauthorized",
  "message": "Unauthorized",
  "path": "/groups"
} 

While using the M2M token I get the result and everything works.

Native call on backends log:
Apr 11 12:39:06 x heroku/router: at=info method=GET path="/groups" host=hero.app request_id=f04a-4304-a47b-035fd0c8f7fd fwd="83.23.100.226" dyno=web.1 connect=0ms service=8ms status=401 bytes=527 protocol=https 
M2M call on backends log:

The two applications are connected to the same database. The config is identical on auth0-s site. I dont know what is happening. Any clues?

Found the error. it was mismatching audience.
