Schedule messages natively in chats and groups

The submitted context

WhatsApp still lacks generally available native message scheduling for ordinary chats and groups. People handling reminders, work handoffs, or different time zones must set a separate reminder or trust an unofficial automation tool. Please add a long-press Send option to choose a date, time, and time zone, plus a Scheduled section where senders can review, edit, send now, or cancel pending messages. Schedules should sync across linked devices and explain what happens if every device is offline. Reporting in 2026 indicates that scheduling is under development but not yet generally available; this request is for a safe cross-platform release.
