[2020] A video of my situation. I can farm nodes in the ship battles, do challenges, but when I play, like the below video is my GAC you can clearly see the battle happening in the background. I enter the battle and this message pops up within 3-6 secs pls help. I have also tried reinstalling the game.

Could you try reinstalling your game from from the Play Store or App Store. Once the game has been reinstalled, leave it on the main Cantina screen for a few minutes to ensure that all of the additional files and assets have been downloaded.
