Why did a tenant not receive a community announcement?
First check that the tenant is currently assigned to a property on the community page. Page membership follows those properties. A tenant who has moved to a different property may no longer see the page, while a newly assigned tenant can see its post history.
The audience preview distinguishes registered accounts from invitations that have not been accepted. An invited tenant who has not created an account cannot receive the page's in-app or push notification; resend their invitation if needed.
A tenant can mute a page and still read its posts when they open Community. For phone alerts, also check the device's notification permission and the account's push preferences. An in-app notice and a phone alert are different delivery surfaces.
Confirm that the post is published and has not expired. Scheduled posts appear when their scheduled time arrives. For a direct follow-up, use Messages or contact the tenant through your normal communication process.
