Does Firebase 9 actually work for anyone on Expo 43 ?
As per the release notes, Recommended firebase version is now 9.0.2. When you run expo upgrade, we will install the new modularfirebase library in your project if you use firebase
So, I’ve upgraded one of my apps to Expo v43, and given the above, I’ve also ported it to Firebase v9.
Now, regardless of the Expo version I install v9 on (tested with 41 and 43), whenever I try to pull any data from Firestore, it says “Could not reach Cloud Firestore backend ”. Keep in mind that the Auth works, it’s just the Firestore module crapping out.
I’ve tested the following (brand new expo init setups):
Firebase 8 with Expo 41 (everything works)
Firebase 9 with Expo 41 (auth works, firestore doesn’t)
Firebase 9 with Expo 43 (auth works, firestore doesn’t)
Any clue? Is it just me?
Later edit: Just for fun, I’ve installed expo-firebase-starter which has been updated to expo 43 and firebase 9. Now, it doesn’t have any actual firestore code, and so I’ve added some lines, then sent it to a few of my friends to try it out as well.
Same error, firestore client backend could not be reached.

### [REQUIRED] Describe your environment

### [REQUIRED] Describe the problem
I just started updating my code from Firebase v8 to v9 and then started running into this issue (which is weird because it was just working before I upgraded to v9 so I'm pretty sure it's not a network issue)
It seems like some firebase features do work, for eg the onAuthStateChange from firebase.auth, but whenever I try and run a Firestore command it seems to get stuck.
