Hi, thanks for reporting this and welcome to our forums. I understand how frustrating it is to lose H2H stars after being disconnected. Could you please try these steps before your next H2H session:
- Fully close FC Mobile and restart your device.
- Turn Airplane Mode on for around 10 seconds, then turn it back off.
- Restart your router and reconnect.
- If you normally use Wi-Fi, test a match using mobile data or a mobile hotspot. If you're already using mobile data, test another Wi-Fi connection if possible.
- Disable any VPN, Private DNS, ad blocker, proxy, or similar network-filtering service.
- On Android, go to Settings - Apps - FC Mobile - Storage & cache - Clear cache. Please clear the cache only, not your game data.
- Make sure FC Mobile and your device software are fully updated.
