When I’m using the app, firebase will record the information that I am online(online = true). But if I close the app or the internet loses the connection, firebase will record offline(online = false).

Thanks in advance

Hello @maskuullahoa and welcome 👋

Do you _have_ to use Firebase in your implementation?

I think that if you use a cloud variable this would would be a lot easier to set up and to create the logic for.

Thanks,
