Yes - the keyboard is compatible with iPad and iPadOS/iOS devices via Bluetooth and should work with a 9.7" iPad running iOS 16.7.12. Logitech states that the keyboard is designed for iPad and iPadOS devices and supports Bluetooth connectivity and Easy-Switch for multiple devices, allowing use with a 9.7" iPad and iOS/iPadOS versions.
I'm not entirely sure if Logitech explicitly mentions each individual iPadOS minor version (e.g. 16.7.12); the available documentation generically mentions compatibility with iPad/iPadOS via Bluetooth. If you want absolute certainty, I recommend briefly contacting the manufacturer's site or Logitech support.
Hello Pasci
I just had to practise a bit. But if you hold down "opt | ctrl" (key to the right of the space bar) and then press G, the @ appears. 👍🏼
I connected it on my iPad and it works great. Probably also depends on which device you are connected to and which keyboard layout you have set.
Greetings
