Phantom Wallet Not Connecting Properly – Desktop & Mobile Issues

[arfm19]

Summary

We’ve built a Solana dapp and are facing critical wallet connection issues with Phantom:

On desktop:

Phantom does not trigger the extension when "Connect" is clicked

Displays “Connected” with the wallet address even when the wallet is logged out

Token balances (USDC/USDT) show as 0.00

Disconnect button works correctly

On mobile (Safari default, Chrome test):

Clicking “Connect” triggers the Phantom app

The app briefly opens but then returns the user to a new tab, not the original session

Connection fails silently

All code follows the official Phantom documentation and community examples. We’re using @solana/web3.js and @solana/spl-token via CDN.

Example

Available upon request (we prefer not to share our dapp link publicly)

Steps to Reproduce

1- Open dapp on desktop (macOS, Chrome/Safari/Brave)

2- Click “Connect” → Phantom extension not triggered

3- Wallet address appears, but user is not actually connected

4- Balances = 0.00 even with actual tokens

5- On mobile, “Connect” opens Phantom app → redirects back to a new tab, not the one used, and no connection gets established

Phantom Version

Latest extension + latest iOS mobile app (tested across devices)
