Rocket Chat is a widely-used chat platform that can be freely downloaded and installed. If you manage an organization or company, you can explore Rocket Chat as a communication tool for your team or clients.

I can help in:

White label (rebranding) Rocket Chat (RC) Android RN app

Please note the following:

If push notifications for the Android app is not working after setting it up (following the docs), it could be an issue with the server or RN app. In that case, respective dev team should be consulted via their repositories on GitHub or by any other means.
