Vaillant ambisense not working vr50

Hi, I'm new here.
I tried searching existing posts but didn't find a situation like mine.
Last year I installed a Vaillant ecoinwall plus boiler with multimatic vr700/6 controller, connected via ebus.

I have a 3 zone underfloor heating system, the different zone valves are controlled by three different on/off thermostats (non Vaillant). the only zone configured is therefore not associated with the vrc700, but "managed" by the on/off thermostats.
I also have 3 wall radiators (2 bathrooms and 1 tavern) each with its own thermostatic valve.
I purchased the ambisense kit in Germany few months ago, mounted the vr921 by connecting it to the EBUS and downloaded the app.
So far everything ok.
I mounted the vr50 valves on the radiators, followed all the procedures, but the app doesn't see them in any way.
I tried to contact Vaillant support and they told me that since ambisense is not sold in my country (Italy), it doesn't work here :( is it ever possible? Has anyone had such an experience? among other things this type of policy ( geoblocking) is expressly prohibited in the European community since 2018. please help me!!!!
