For the last 12 hours we have been getting a lot of Transport errors with "HTTP Response code: 418". That made sync of users data practically impossible.
Has anything changed in how clients should communicate to the API or is it temporary error related to Wednesday's release?
We solved the problem by changing URL for UserStore from https://www.evernote.com/edam/user to https://www.evernote.com//edam/user (used by official SDKs)
