If nothing happens when you connect a wallet to a Ronin dApp, it's possible that other wallets installed on your device are interfering with the connection request.
As most wallets uses different types of EIP standards, there are times where two wallets override each other and interfere with the connection between dApps and the intended wallet.
How to Fix Wallet Connection Issues
Step 1: Look for your browser's Extensions settings. On most browsers, this is usually listed as "Extensions".
Chrome/Chromium-based browsers: Click the ⋮ menu and click Extensions.
Edge: Click the … menu and click Extensions.
Firefox: Click the ≡ menu, choose Add-ons and themes. Go to the Extensions tab.
Step 2: Disable the other wallets in the Extensions list. You can usually do this by switching the toggle to an "off" position.
If you are connecting the Ronin dApp to the MetaMask Wallet, leave only the MetaMask Wallet enabled like in this screenshot.
Step 3: Clear the cache of your browser, restart the browser, then try to attempt the transaction/connection again.
