AlphaWallet signatures not valid for limit orders

[bitcoinwarrior1]

Hi All, when trying to sign a limit order using AlphaWallet, we get back this error: AlphaWallet/alpha-wallet-ios#1290

When debugging in the mobile browser, there is no error on the console.

Any ideas?

"I have problem when signing message from alpha wallet. We try to use imlementation: web3.eth.sign(message, address). For metamask, they keep the message and sign message with private key inside their app. In some wallets (Imtoken) they add prefix and use new_message = hash(prefix, message) to sign with private key.

I'd like to ask which output in Alpha wallet when I sign message? I've tried several ways, but I didn't figure out."
