React Native repeated timeouts writing collection to firestore@firebase/firestore: Firestore (8.4.2): Connection WebChannel transport errored

• Browser version: Chrome 90.0.4430.85
• Firebase SDK version: 8.4.2
• Firebase Product: Firestore

Hi, I hope this is in the right place.
I am trying to write a user to a firestore collection from a react native app. The user gets created in firebase fine under authentication but it then hangs on the firebase.firestore().collection('users').doc(uid).set('data').

After a few minutes I get a warning: "firestore@firebase/firestore: Firestore (8.4.2): Connection WebChannel transport errored"

I will continue getting this warning every few minutes and sometimes after 20 mins or so the collection might be written to firestore.

I assumed it might have something to do with another dependency but I created a basic app that just calls the relevant code on load and the same warning occurs. I've tried on both a physical device and android emulator.

if (!firebase.apps.length) {

export { firebase };


import { StatusBar } from 'expo-status-bar';

Hi @DeanMcAuleyH, please try to use experimentalForceLongPolling in your Firestore settings. See below:

firebase.initializeApp(firebaseConfig);
firebase.firestore().settings({ experimentalForceLongPolling: true });

[DeanMcAuleyH]

@looptheloop88 Thanks very much for your answer. This appears to have fixed my issue. I actually saw this in a stack overflow answer but the author called it a temporary solution so I was unsure if I should use it and if there was maybe an official way of getting past it.
