Anybody else not able to get Touch ID to make purchases from the iTunes and App Store apps on their iPhone? I'm trying to determine which tweak I've installed recently is causing the problem, but it's odd that Touch ID is working everywhere else (Evernote, Dropbox, 1Password, VirtualHome). The Touch ID prompt appears, but pressing my finger to the sensor doesn't validate the purchase. The prompt just sits there. Edit: well, uninstalling VirtualHome & the SubtleLock iOS 8 beta fixed it. Now I have to figure out which one was the culprit.
