问题
App is getting error firestore not able to reach backend, internet is working perfectly (can reach google.com), After searching for solutions I found that there is a option of
firebase.firestore().settings({ experimentalForceLongPolling: true });
in firestore js sdk but not in android, Questions:
- Is this the right solution
- Whats the android equivalent

It worked when I changed the network from wifi to cellular, can we achieve this through code, anyhow detect firebase connection is failing then ask user to switch network or programatically change network ?
There exists a unanswered question : Couldn't reach cloud firestore backend Android (21.3.0)
