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
I'm trying to add an animated sticker of 500.438 bytes (504 KB), it passes all the validation checks on the sample app but fails to import to WhatsApp.

I get the error "The size of one of the stickers is too big".

Can you please confirm which is the correct maximum size? 500 * 1024 bytes or 500 * 1000 bytes?

Thanks.

Here's the sample project
