If you are looking for "exclusive" features (like hidden chats or themes) rather than just an old version, people often use or the WhatsApp Beta via TestFlight. These are official, safer, and often have features the standard version lacks. To help you get exactly what you need, let me know:
Every iOS app must be signed by Apple to run. When a new version of WhatsApp is released, Apple stops "signing" (authorizing) the old version. Currently, WhatsApp is on version 24.x or 25.x. Version 2.36 stopped being signed over a decade ago. whatsapp 236 old version download for iphone exclusive
