What can i do?

Hey @tech1

Please check any of the Flutter example apps from web3auth-pnp-examples/flutter at main · Web3Auth/web3auth-pnp-examples · GitHub.

Looks like a misconfiguration.

thanks for reply
but It seems there’s no problem with configuration.

I have 2 test devices. 1 with SAMSUNG mobile, and 1 with LG mobile.

With testnet, both devices work fine.

With mainnet, LG device works fine.
but SAMSUNG makes the error above.

I don’t understand why this happens.
Can you please check further with this information?

Thanks in advance
