The service begins at 9:30 in the sanctuary. Ari reads his parashah at about 10:15. Kiddush follows immediately afterwards in the social hall — please do stay.
WhatsApp: sent by the platform once the sender is switched on. Email and SMS go from the platform, with consent and quiet hours per country. WhatsApp is a channel the platform sends and receives on too — once the WhatsApp sender is switched on and the guest has agreed to WhatsApp in their own right. Until the sender is on, WhatsApp opens on your own phone with the message already written and you press send. Invitations to United States numbers never go as WhatsApp; they go by text or email instead, and the guest record says why.

Grandparents, a congregation and a room of thirteen-year-olds are not one audience. The briefing named them; the platform sends to them.
