I recently signed up for an account and have started using the Evernote API. I am building an app for my personal usage, so the developer token authentication is ideal for my use case. I am able to create and use a developer token in the sanbdox, however when I go to https://www.evernote.com/api/DeveloperToken.action I receive the following error "Update: the creation of developer tokens is temporarily disabled." I don't want to build my app in the sandbox with this authentication technique if it won't be available in production. Is this a common error and is there a known fix? Based on my research it seems this has happened several times in the past and has eventually just been fixed. Is that expected to be the case again?
