Logitech makes the following specifications: Windows®, macOS, iPadOS, Chrome OS™ & Linux®.
Digitec only writes: Linux, Chrome OS, macOS, Windows 10 - so iPadOS is missing here.
But I think Logitec has it right. [https://www.logitech.com/de-ch...]

Haii :D

No, operating system compatibility: Linux, Chrome OS, macOS, Windows 10

And Yes, up to 3 devices.

You will find most of this information when you open the specification tab ;)
