Uninstall/reinstall sticker pack in iOS 10
I have been having some unusual issues with the new stickers in Messages. I had a few different packs installed and have found that two of the packs don't appear in the "Manage" area of the Message Store. However, the store shows them as installed. I've disabled every pack I've installed, which seems to have made those able to be reinstalled, except for those two which are seemingly invisible.
I haven't been able to find any other method to disable/delete these sticker packs from my device. They are Super Mario Run Stickers and Stickmappers.
I have a second phone for work and no problems with any of the new Messages features there. Wondering if there is a way to somehow reset the Messages Store to default or another way to delete/manage installed packs.
Thanks!
