The first page is rendered to a cover image members see in the bell and (if enabled) the carousel.
Imagery — optional
Preset banners render inside the app only. They are not used as a carousel cover (that needs an uploaded image or a PDF cover).
Audience
Tick the sections this is for. Leave all unticked to send app-wide.
Deep link — what a tap opens
Rendering of image banners and deep-links in the member apps ships in a later release; the push and bell text work now, and today's apps land on the section they already understand.
Placement & expiry
Flags this announcement for the home carousel (needs an uploaded image or a PDF cover). The carousel tile appears once the next member-app update ships — the push to the bell goes out now either way.
After this day the announcement is treated as dead — a delayed push is skipped.
