Mismatch when attacking

Hi sir…
Why recently has there been a frequent mismatch when I’m attacking, and why isn’t my attack during a mismatch counted? and even many people who complain because of this problem, please help to fix this problem as soon as possible. MAZHAN.

Recently we did maintenance break to fix some issues and significantly improve battles stability. Now there should be less “checksum mismatch” errors and freezes in the clouds.
