No, it's for the Surface Go series, not the Pro version

I don't know. the keyboard didn't fit on my device, I returned it. I could have seen it if I had looked at the interface better. hope that helps...

No. This Type Cover is only suitable for the smaller "Surface Go" series (10.5"). I have already used this keyboard with the Surface Go, Surface Go 2 and Surface Go 3.

No! I just have difficulties with it

According to the manufacturer, this keyboard is compatible with your Surface Go 3.

This Microsoft Surface Go Signature Type Cover has the German keyboard layout.
