Hi all!
We are submitting a new update, this will be our second now with Sticker packs included.
We went to upload to Application Loader and now getting this error from iTunes Connect:
Invalid iMessage App - Your iMessage app contains an invalid sticker pack. The app may have been built or signed with non-compliant or prerelease tools. For more information, go to developer.apple.com.
AFAIK there's been no changes to our Stickers Pack, only changes are in-game.
Anyone have any ideas or seen this before?
