Only receives one cookie in fetch response on Android but not on iOS

When I send a POST fetch request to my website to login it all works on iOS. The fetch response set-cookie have all the cookies I need to proceed and make future requests. The problem is on Android I only receive one cookie in set-cookie, even though there is more. It seems like it gets cut and I can't seem to access the raw response.

My fetch code:

    const myRequest = new Request('MYURL', 
      {method: 'POST', body: parameters,
         headers: {
             "Referer": 'MYURL.com/login',
             'Origin': 'MYURL',
             'Content-Type': 'application/x-www-form-urlencoded'
    }});
    fetch(myRequest)
      .then(
        function(response) {
          try {
            console.log("JSON RESPONSE: " + response.json());
            console.log(JSON.stringify(response, null, 2));

            console.log(response.headers.get('Content-Type'));
            console.log(response.headers.get('Date'));

          } catch(err) {
            console.log("ERROR: " + err);
          }
        }
    )
    .catch(function(err) {
        console.log('Fetch Error', err);
    });

I know that android gets correctly logged in cause the server redirects me to the menu page and also recognizes the clients personal ID.

Here is the response from iOS(the one that works):

"set-cookie": "session=CENSORED; Domain=.MYURL; Path=/; HttpOnly, clientID=123; expires=Thu, 07-Nov-2019 09:27:20 GMT; domain=.MYURL; path=/",

Perfect response. Everything works.

Here is the response from android:

"set-cookie": "clientID=123; expires=Thu, 07-Nov-2019 09:34:00 GMT; domain=.MYURL; path=/",

I've tried for several days to understand the problem but to no avail. I've tried to test cookies without httponly to see if that was the error but no.

I hope some experienced react-native users can shine light on this problem. I haven't experienced it before when I created native apps for android and IOS. Only with react-native. :-(

I hope to get to this to work since I would rather avoid using native code for this small part.

EDIT: Tested fetch function with reddit login api and same problem occurs. Only 1 cookie in response set-cookio on Android but all cookies shown on iOS.
