The smiley ones don't seem to work well and freeze my iMessage window. Also, they say "add" in the App Store but they are already downloaded and tapping the button doesn't do anything. Is there a way to delete them? I wanna delete and update them again. But they don't seem to work like normal apps.
My iOS 10 came with the Mac ones preinstalled it seems. I have them but never downloaded them to begin with.
If anyone can find a way to delete them, that would be great.
Edit: figured it out. Tap and hold on them till they wiggle.
