A group of Microsoft Products and technologies used for sharing and managing content, knowledge, and applications.
I think the AI-generated response already covers the topic quite well, but I'd like to clarify and add a few points that may help.
AI stated that “On mobile, users can only turn all Teams push notifications on or off for apps on Teams.” However, I would like to clarify this more precisely to avoid misunderstanding. This does not mean users must disable all Microsoft Teams notifications. On Teams mobile, users cannot selectively enable or disable each Viva Connections notification type as they can on Teams desktop or web. Instead, they can toggle push notifications for Apps on Teams, including Viva Connections. Depending on the Teams mobile version, this setting may appear under Settings > Notifications > General Activity > Apps on Teams. Even after push notifications are disabled, the notifications may still remain visible in the Teams activity feed.
For missed-news emails, Microsoft sends no more than one automatic news digest per week, containing up to 10 posts. The digest may include relevant published news that the user has permission to access but has not yet viewed. If no relevant, unviewed news is identified for that user, no digest is sent. Therefore, a news post published in the previous week may appear in a later digest if it remains relevant and unviewed. However, Microsoft does not document a fixed seven-day inclusion window or a universal delivery schedule for all users.
Microsoft also notes that notifications based on the “people you work closely with” relationship are determined using the author’s top 100 collaborators. If the author has more than 100 collaborators, Microsoft Graph selects the most relevant collaborators for notification purposes. In addition, notifications triggered by publishing a News link, rather than a standard SharePoint News page, are available only in Microsoft Teams mobile. These factors may help explain why users do not always receive the same SharePoint News notifications, even when they appear to have similar site access and notification settings.
I hope this provides some additional context and helpful information. If anything is still unclear, feel free to leave a comment and I'd be happy to clarify further.
