SDK version 11 issues

Hi Silanis team- me again :) We just updated to the .NET SDK to version 11.0.0. Since then we are getting the following error: Could not create an authentication token for a signer. Exception: The remote server returned an error: (500) Internal Server Error. HTTP POST on URI https://sandbox.esignlive.com/api/signerAuthenticationTokens. Optional details: {"messageKey":"error.internal.default","technical":"Unrecognized field \"sessionFields\" (Class com.silanis.esl.api.model.auth.SignerAuthenticationToken), not marked as ignorable\n at [Source: java.io.ByteArrayInputStream@7a273704; line: 1, column: 96] (through reference chain: com.silanis.esl.api.model.auth.SignerAuthenticationToken[\"sessionFields\"])","packageId":null,"entity":null,"code":500,"message":"Unexpected Error. Our technical staff have been notified and will look into the problem. We apologize for any inconvenience this may have caused you.","name":"Unhandled Server Error"} Exact same error happens also on the SignDocuments(...) function (ie., not calling the token service explicitly). Have you seen this before? Anything we need to change with the new SDK? (I'd look at the code, but i don't think the new version is out on Github yet) thanks, =maina)
