iPhone 5 - Keyboard Shortcuts stopped working

Hi Community,

my iPhone 5 keyboard shortcuts stopped working since a couple of days. Moreover the same problem occurs with my iPad Mini 2.

I didn't change any settings or whatsoever.

Also very strange is, when I enter the keyboard shortcut settings, the whole setting app becomes super slow or crashes. And editing the settings is also super slow... I mean 15sec. after-click-reaction slow...

Anybody has the same problem?
