Sync issues with Binance are usually caused by a network error or the app being sent to the background during the sync process. Follow these steps to resolve it.
Perform a full manual sync: Go to Settings > Connections, find your Binance connection, and tap the circular arrows to start the sync.
Keep Delta in the foreground during the sync: Make sure the app stays active and your device screen does not lock. If the sync takes longer than 30 seconds, keep the screen active until it completes.
If syncing multiple Binance connections: Sync them one at a time and wait a moment between each sync to avoid hitting Binance's rate limits, which can temporarily block syncing.
Check your network connection: Switch between Wi-Fi and mobile data to rule out connection issues. Avoid using a VPN, or ensure your connection is stable.
If the issue persists after following all these steps, please contact support and we'll investigate further.
