Hello everyone. Was doing some testing for our chat app using Ringcentral.NET and the online API explorer. The syncType enum of "ISync" for the path "https://platform.devtest.ringcentral.com/restapi/v1.0/account/accountId/extension/extensionId/message-sync" is bugged and will always generate an error. Since the default type of sync is FSync, this makes it impossible to use incremental sync with the Messages Sync API. As we can't do incremental sync using the API, we are going back to the Message Store API paths for messages. Please fix the bug or let other developers know that it is broken.
