Conga Composer | Action Required: Connected App Configuration Update

This incident has been resolved.

Following the Composer 8.298 release, Salesforce administrators must update the OAuth policy settings for the Composer Connected App. Until this change is made, Composer merges may fail or return authentication errors.
Who is affected: Salesforce orgs running Conga Composer 8.298 or later that have not yet updated their Connected App settings.
