While seting up an 10.5″ iPad Pro in combination with the Logitech “Slim” Combo, I noticed something weird. Although the keyboard layout in Settings.app was clearly set to “German” and “QWERTZ”, the keyboard behaved as it I had configured it as “QWERTY”.
I tried switching the layout in Settings.app between “QWERTZ” and “QWERTY”, and back. No luck. I tried removing the keyboard in Settings.app.
After I set it up again, the layout was still set to “QWERTY”. Positively weird! This issue even survived several reboots. I had never experienced anything remotely like that.
In an act of desperation, I hooked up a spare (Mac) Magic Keyboard to the iPad via Bluetooth. And yay, “QWERTZ” was back in town. But still, why does the Logitech keyboard behave so weirdly?
Let's check again. And thus, I engaged the magnetic connection between the Slim Combo's keyboard and the iPad again.
Guess what? It worked. Just like that.
Frankly, I have no explanation for why I had to hook up the Magic Keyboard to make the already installed keyboard work in the intended way. But that's exactly what happened.
