Be careful!
If I want to unlock all fonts then I am forwarded to the app cool font pro for iOS 8!
WTF? I have installed iOS 10.0.2 on an iPad Pro 12!
The last update of that app was in 2015; the recent update of this app is 2016! This is more then strange. Even the last comment on the PRO Version is not answered yet (German öüä is missed).
