React-native-firebase: Firestore offline persistence, fromCache is always false

[eugenecp]

Issue

I already set my internet access to Airplane Mode, however the metada fromCache is always false.

ref.onSnapshot((qrySnapshot) => {
console.log(qrySnapshot.metadata);
});

android log

(Update)
It seems, the app just needed to be restarted for the onSnapshot to behave properly.

@eugenecp I am reading that the module does not support enablePersistence. So, it does support offline caching for firestore?

Offline persistence doesn't seem to be working for firestore. If I turn off wifi, my data stops loading and I get Network Request Failed error. If I call firebase.firestore().enablePersistence() then I get Persistence is enabled by default on the Firestore SDKs

Offline persistence is working for authentication though. I just can't load any data from firestore that should already be cached.
