Is PiFace Digital 2 compatible with Raspberry Pi Zero W rev 1.1?

Can anybody definitively say if the "PiFace Digital 2" is compatible with the "Raspberry Pi Zero W rev 1.1" or not ?

I cannot find any Information on the web – besides a mention in a Book behind a paywall:
https://subscription.packtpub.com/book/hardware_and_creative/9781786463852/7/ch07lvl1sec88/interfacing-the-piface-with-the-rpz

The error message i get from python is:

pifacedigitalio.core.NoPiFaceDigitalDetectedError: No PiFace Digital board detected (hardware_addr=0, bus=0, chip_select=0).

I’ve tried everything I could find on the web, including:

• different raspberian versions from lenny to buster
• confirmed that spi is enabled
• checked the jumpers on piface
• different versions of pifacecommon (github, pip- & raspberian-packages)
• different spi frequencies as described here: https://github.com/piface/pifacecommon/commit/d4c568926e49dc75a983e2fed41b79ebf317b10d?diff=unified
• checked syslog for any error-messages

As @Dougie suggested:

Update:

Did that same as above on a Raspberry Pi 3b and it just worked – so there are two options – pi zero is not compatible or my pi zero is broken
