Auto-lock setting not available in iOS version 17.4.1?

Hello Community,

I have an iPad 8th generation with the current iOS version 17.4.1

Before the last software update I performed, I could manually decide after how many minutes the iPad would automatically turn off.

➜ Settings – Display & Brightness – Auto-Lock

But when I go to this setting now, I don't have the option to click "Auto-Lock" – it says 2 minutes. Since that's too short for me, I'd like to change it.

I look forward to your answers!
