More than once, I've unlocked my iPad to see an app and a folder immediately show the updating symbol. I don't know which app in the folder is updating, but the one not in the folder is Memrise.
I looked in the preferences, and Memrise is not even listed in the long list of apps that have settings. There is no settings icon on the main screen of Memrise, and I can't log in until I look up my password. This never happened before the iOS 10 upgrade.
What might this be and how to stop it?
