Server Connection issues – Pokémon TCG Online Review

I really enjoyed the game, but the server constantly loses connection.Even when I’m close to the modem/router the server is still having trouble keeping the connection in both the training challenges in the verses I’m not sure if there is an issue with the app, But it has made me lose challenges because of poor connection. Please inform me if that issue is more on the app or the device used to play the game. Thank you!
