Sync Not Working Between Devices
Steps to fix device-to-device sync issues and get your data synchronized.
Quick Fix
Before detailed troubleshooting, verify these basics:
- Both devices have Lova open
- Both devices are on the same WiFi network
- Devices are paired (Settings → Sync → Paired Devices)
1 Network Issues
Some networks block the discovery protocols Lova uses:
Corporate/enterprise networks
Often block device discovery
Hotel WiFi
Isolated guest networks
Coffee shop networks
AP isolation enabled
VPN connections
Routes traffic differently
Home Network
2 Check Device Pairing
Verify your devices are properly paired:
- 1 Go to Settings → Sync → Paired Devices
- 2 Look for your other device in the list

3 Firewall & VPN Settings
On desktop, firewalls or VPNs may block sync:
macOS
Allow Lova in System Preferences → Security → Firewall
Windows
Allow through Windows Firewall when prompted
VPN Active?
Temporarily disable VPN on both devices during sync
4 Manual Sync Options
If automatic sync won't work, use these alternatives:
QR Code Sync
Direct encrypted connection between devices
Backup File Transfer
Export and import encrypted backup
QR Code Sync Steps
- 1 On device A: Settings → Sync → Show QR Code
- 2 On device B: Settings → Sync → Scan QR Code
- 3 This establishes a direct encrypted connection
5 Re-Pairing Devices
If all else fails, remove and re-add the pairing:

- 2 Remove the other device from the list
- 3 Re-pair using QR code method
