[iOS] How to make WhatsApp to recognize the same sticker pack and just update it

[DrAma999]

Specifications
OS Version: iOS 14.4
Device Manufacturer: Apple

Stickers

• My stickers do comply with the sticker requirements (512x512 and < 100 KB)
• My tray icon does comply with the requirements (96x96 and < 50 KB)
• I am using WebP images for stickers.
• I am using PNG images for stickers.

Problem Description
This is more an improvement than an issue.
On my application I would like to give users the opportunity to create animated sticker and add them to a specific sticker pack. My application basically creates a "triggered" version of you selfies, then you can share the video, the image, or an animated sticker from the video.
Everything works except that I've found some constraints very restrictive for my use cases.

1. A sticker pack must have at least 3 stickers. Since my sticker is generated at runtime from just one picture the only solution at the moment is to replicate the same sticker for three times.
2. Even if the sticker pack has the same name, same identifier, as another one created before, whatsapp recognizes it as a new one, resulting in a new sticker pack each time a user want to share its sticker.

Considering that I'm wondering if there is a way to just share ONE sticker and a way to just update a sticker pack if the name and the identifier are the same.

Reproduction Steps
Share a sticker pack multiple times

I think there was a bug with WhatsApp iOS app, where an update is being treated as a new pack, it is now fixed. Please upgrade your WhatsApp and try again.
