When i am playing on LTE on my phone when i lose the score doesnt appear and a message appears that the internet connection is not stable and when i tap retry it shows error 400 returning to start screen

Sounds like the server did successfully process the request, but the network was too unstable for it to receive necessary data from the server. As we do have measures in place to prevent repeats of this kind of request, your progression should have saved despite the error.
