Hi D2L Team,
Based on the few escalations reported by customers on the Pearson side, it appears that some users are encountering the following error during the grade sync process.
LmsGradePushException: 409 Conflict: [Requested score timestamp is less than or equal to the timestamp of last score received]\\n\\tat
The examples and details are provided below.

Thanks!
