Honest answers, including exactly what a WhatsApp message can and can't do, so there are no surprises either way.
A preview link usually arrives within about 10 minutes. Reply "approve" and it's live a few minutes later.
You'll get a WhatsApp message letting you know it's been flagged for a developer to look at personally, rather than the assistant guessing and getting it wrong. It's usually handled within 72 hours, with a confirmation once it's done.
None of this is hidden or a bait-and-switch. It's simply outside what a text message can safely and reliably do, and we'd rather tell you upfront than overpromise.
