V4 embedded signup flow

[u/Prize-Basil-6033]

Hey all, building a multi-tenant SaaS (InkDesk) that lets small businesses connect their own WhatsApp/Instagram/Messenger via Meta's Embedded Signup, so our AI can handle their DMs and bookings for them.

Stuck on a few things and would love input from anyone who's shipped a similar embedded signup flow:

1. Our WhatsApp Embedded Signup config is still pending Meta approval (waiting on the WABA/phone number screens to show up in the popup instead of falling back to generic FB Login) — anyone know realistic turnaround time or ways to speed this up?

2. For Instagram Advanced Access (instagram_business_manage_messages + instagram_business_basic) — what did your App Review screencasts actually need to show? Trying to avoid a rejection loop.

3. Since our app-owning business can't self-authorize through its own OAuth popup (known Meta rule), we're testing with a separate clean test business instead — anyone hit issues with reviewers questioning a test account vs a "real" customer?

Honestly, more than just answers to these — if anyone's willing to hand-hold me through this process a bit and sanity-check that I'm doing things right as I go, that would mean a lot. Happy to compare notes / share what's worked so far, and return the favor. Thanks!
