Firestore not working on android emulator new Expo Go app and 46.0.7 SDK. Throwing Errors

See original GitHub issue

Summary

It seems like the new Expo Go app on android studio emulator can’t reach internet connection. I have a strong internet connection. But It is throwing these errors:

ERROR  [2022-08-15T19:48:15.318Z]  @firebase/firestore: Firestore (9.9.2): Could not reach Cloud Firestore backend. Backend didn't respond within 10 seconds.
This typically indicates that your device does not have a healthy Internet connection at the moment. The client will operate in 
offline mode until it is able to successfully connect to the backend.
 WARN  Possible Unhandled Promise Rejection (id: 0):

But working on the real device, there are no errors.

What platform(s) does this occur on?

I was able to resolve this by replacing

const firestore = getFirestore(app)

with

const firestore = initializeFirestore(app, { experimentalAutoDetectLongPolling: true })

as indicated here.

Finally! I have tried a lot of possibilities but none of them worked… That one works like a charm! Thanks!!
