Hi, we are having some problems when users are using authereum wallet with zkSync.

It looks like this issue is caused by EIP1271 signature verification. I am wondering if it can be because there are two types of EIP1271 signatures that your wallet can produce: one is 65 byte long other is larger.

We use user signatures of the message to check for correctness and it fails sometimes. Can you please explain how user signatures work in authereum?
