Does not work

I have an HP laptop HP 15t-dy 100 that I bought new in the past 2 years. 10 gen i7.

After following all the instructions and download and install the duet software on my laptop, I connect my ipad 11 pro 2018 to it, and the app keep saying Could not verify on the second step, although the computer show notification from duet that it has detect new ios device connected.

I do a search online and there seem to be no support or mentions regarding this Duet for HP app anywhere, even on the duet website.

Not working

This application is not working. I have HP OMEN computer and I tried to use my iPad mini 2 as a second monitor but the application on both devices were not able to connect to each other.

The iOS app couldn’t verify my computer as HP, and the computer app couldn’t detect my iPad.
