Can I do an update for my existing sticker pack (which is already for sale in the app store)?
I want to add a few stickers so that new customers get more stickers but so that people who have already downloaded the app will be able to 'update' their sticker packs and get the additional stickers for free.
How do I do that? Is it possible?
Thank you so much for your help. I'm new to this so I realise it's probably a simple/silly question.
