[iOS] Empty packs after pack update

[guidev]

Specifications
OS Version: iOS 13.7 WhatsApp Version: 2.20.92 (App Store)

Stickers

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

Problem Description
Hello,

There's an issue when trying to add the same pack (same identifier), instead of being recognized as the same, the pack is unexpectedly added again to WhatsApp. This results in duplicate packs, one of which (the "old" one) appears empty.

Reproduction Steps
Reproducible with the sample app:

1. Open the sample app
2. Tap on Add to WhatsApp
3. Tap on Save on WhatsApp
4. Repeat from 1.

You now have two stickers packs, one of which is not functioning.

I've attached a video.

Hi, This is an issue with iOS 13 update, where bundle ID is no longer visible to our app. We will fix.

Hello,

My question seems related to this issue, so I'm posting it here: I am wondering why it seems not possible to know if a pack has already been added to WhatsApp? There is a method WhitelistCheck.isStickerPackWhitelistedInWhatsAppConsumer(...) on Android, which is very convenient so we can prevent our users from uploading the packs several times (with a good UX).

Thanks

I also agreed with @JeanCarrot need to same way with Android.

I received a bug report from one user of my sticker app that updating a pack does not work anymore, instead it creates a new one. This seems to be a regression still in place in version 2.20.120.

Could you file an issue with the engineering team so they get notified of this bug?

Hi, Same here on iPhone Xs Max (iOS 14.4). Is there any update for this issue? @simonzhexu

Whatsapp for andorid has more properties like "image_data_version" and "avoid_cache" for exporting sticker pack. Do Whatsapp for iOS needs set more properties for this issues?

I have the same case.

Hey guys, we are aware of this bug, it happens on iOS 13+ due to changes in API. I will prioritize finding a fix and will update you as soon as I can. Thanks for your patience
