Viva Engage mobile app will reduce reply notification volume by only notifying users of direct involvement (starting conversations, direct replies, @mentions). Automatic subscriptions from reading, commenting, or reacting will stop. The update rolls out worldwide from July to August 2026, requires no action, and keeps existing admin controls unchanged.
