This looks like a common EVM wallet connection issue on Brave, especially with Uniswap V3/V4 pools on Arbitrum/Base. CTRL wallet (likely WalletConnect-based) can conflict with Brave's privacy shields.

Quick fixes to try:

• Disable Brave Shields (lion icon > Shields down) on uniswap.org and app.leodex.io.
• Clear Brave cache: Settings > Privacy > Clear browsing data (cache only).
• Switch to MetaMask extension as alternative—connect via WalletConnect if needed.
• Ensure Arbitrum network added in CTRL; reset connection in wallet settings.

Similar wallet conflicts hit LeoDex recently; migration UI at https://wleo.io/sleo works better post-update. Check that for staking ops.

If persists, share pool address for specifics.
