Sui Wallet on smartphones does not connect with external browsers like Chrome. Instead, open the Sui Wallet app and navigate to the 'Apps' tab. From there, you can type the app address and connect directly using the built-in browser in the Sui Wallet app. If nothing is popping up when you try to connect, make sure you're not using an external browser. Sui Wallet includes its own browsing capability specifically for interacting with dapps.

You shouldn't use another browser like Chrome for connecting your Sui Wallet. The wallet has an in-app browser precisely for these purposes, so access the dapp through that within the app itself.
