The Store icon of my iPhone's Messages app has been displaying this red badge for as far back as I can remember.
When I open the Messages App Store, I can't find any updates or new information that the badge might relate to.
The only tip I got from people so far was that it might be related to pending updates of apps that provide stickers; I have made sure to bring all apps on my iPhone up to date, but the badge persists.
What does the badge on the Store icon indicate?
