After a year of not using my Parity Signer, I attempted to approve a transaction using it. Initially, the signer displayed an error upon scanning the transaction QR code. In response, I updated the app assuming it needed the update. After updating, I successfully restored the Parity Signer using the mnemonic phrase.
However, I'm encountering a new problem: when I try to sign a transaction, I'm faced with the message "Transaction author public key not found." I'm seeking guidance on how to resolve this issue. I appreciate any assistance or advice. Thank you.
