Project War Mobile

I could not even begin to play this game. It loaded up just fine and then it asks me what server so I girl choose the United States and it won't let me select any server. I went to the play store Google that is and it says that my device that I'm using is no longer compatible with this game, even though it loaded up just fine. Does anyone have any ideas I would really like to try this game out. My device that I tried it on is a ONN tablet camp rember the entire name of it but it's like a 2022 or a 2023 ONN tablet.
