I recently bought an iClever BK18 keyboard from Amazon, which has a touchpad that also functions as a number pad. Oddly, I don’t see this keyboard here on the iClever website. The keyboard works well on a Windows PC, but on my iPad, the touchpad can’t click on anything. Other touchpad functions work fine on the iPad — moving the pointer around, swiping to scroll, two finger zooming on photos — all work except the click. I can even switch to the number pad, and that works fine. Is there any fix for this non-clicking behavior? 

I am using an iPad mini 7 (2024 version with A17), and running iPadOS 18.1.
