Railway Wallet stuck on “Railgun Balances updating: 50%” / “Pending Balances” on Arbitrum (ETH + DAI)

Hi team, I’m experiencing a persistent issue with Railway Wallet on Arbitrum. I’m posting here because the Railway-Wallet repository has Issues disabled and no support channels are available.

Problem: Balances cannot update across multiple devices. Funds are stuck in “Pending” for 12+ hours and cannot be shielded, unshielded, or moved.

Main desktop: stuck at “Railgun Balances updating: 50%” indefinitely
Mobile + second desktop: balances update, but then remain stuck as “Pending Balances”

Troubleshooting attempted:

• Switching RPC endpoints
• Re-Scan Private Balances
• Generate All Private POIs
• Fresh install on another computer
• Fresh install on iPhone (same issue persists)

Network: Arbitrum
Tokens affected: ETH and DAI

Funds are effectively stuck because the wallet cannot complete the balance update.

Could this be a RAILGUN engine issue on Arbitrum (e.g., POI sync, proofs, other), or is this a known wallet-client problem?
Please help. Any guidance or next steps would be greatly appreciated.

Thank you,
T
