To receive notifications via the Consent Event Stream, users need either the ReadAllData or the PrivacyDataAccess permission assigned to them. Previously, this requirement was documented but not enforced. To resolve any disruptions that your users experience as a result of this change, assign one of the applicable permissions to them.
Where: This change applies to Lightning Experience and Salesforce Classic in Enterprise, Performance, Unlimited, and Developer editions.
Who: This change impacts users who received notifications via the Consent Event Stream without having the documented permissions assigned to them. Notifications are interrupted for those users.
How: To re-enable Consent Event Stream notifications, assign users the ReadAllData or PrivacyDataAccess permission with permission sets or profiles (can be outdated or unavailable during release preview).
