Careful if the iOS developers/fans see this, they'll get loud claiming they had features before android lol
Anyway, I didn't have a messages notification. But I did have a random google play update notification a couple months ago. It wasn't apart of App Store. It never executed. It didn't have any data other than saying it was an available update. Never had it reappear, never had it before. Been using GOS since the 7 series.
