This has happened twice today. I attempt a ship arena battle, then the load screen is on for ~ 1min. I try to pause game by minimizing, then return and a normal pre-ship arena battle screen comes up. In which I attempt the battle again and then the game informs me that it must reset. I’ve lost two battles for this.
@stuck2510 From the image, you posted it appears that you are having connection issues. I would suggest trying the game on wifi and data to see if the issue reappears.
