This happened to me just today as well. I could still play Battle of Warships this morning. Then an update came out. I updated it, and I can get to the Battle of Warships loading image, but it doesn't load. I waited 15 minutes and nothing happened. Then I uninstalled and reinstalled the game, but it was still the same. I use a MotoE2. Maybe the server for my phone is not supported yet? I used a different Wi-Fi to update it? My phone is no longer compatible?
I would love help because I really like this game!
