1. Network problem: If you are fighting online, it may be that the network connection is unstable or the delay is large, which makes it impossible to read the war zone information. You can try to reconnect to the network, or wait a while and try again.
2. Game version mismatch: If you and your opponent have different versions of the game, you may not be able to read the war zone information. You can check whether the game version is consistent and try to update the game version.
3. Game defects: Sometimes there may be some defects or bugs in the game itself, which makes it impossible to read the information of the battle area. You can try to restart the game or contact the game customer service staff for consultation.
