Connect CatchUp to your WhatsApp once: a code on your phone, or a QR on a laptop.
On a phone the page shows a code; on a laptop, a QR (see below).
The page says Connected. and your new CatchUp group in WhatsApp says ✅ WhatsApp connected. In Linked devices CatchUp shows as Google Chrome: do not log it out.
In WhatsApp on your phone: ⋮ (Android) or Settings (iPhone) → Linked devices → Link a device, and point the phone at the QR. Scan it from inside WhatsApp, not with the camera.
A code works for 3 minutes. Tap Get a new code while you are on WhatsApp's code screen.
Right: the 8-letter code goes into WhatsApp. The 6-digit code from your email is only for signing in.
Use the one with this number: WhatsApp or WhatsApp Business.
WhatsApp allows 4 linked devices. Log one out under Linked devices, then link again.
Open getcatchup.in on a laptop or another phone and scan the QR instead.
