How to Reconnect a Canvas Assignment to VeriCite LTI - June 2016 Update
The Canvas API for grade and comment syncing requires a consistent URL from VeriCite. VeriCite staff detected errors on 2016-06-03 when syncing grades and comments via the Canvas API. Updated VeriCite code was put in place at 07:00 EDT to resolve sync issues. Please ensure that the LTI “Launch URL” is set to https://app.vericite.com/vericite/
