Sorry but I don't know the exact reason for this error, I have not meet this error before. I will try to find the reason soon.

Are u using the same wallet address in extension? This is an error in your contract, could you show us the contract code that using "apply" method?

Hi, could you give us your Dapp url?

Do you want to save the note just in wallet or save it into smartcontract?
