Qubino flush dimmer - can’t get input 2 working

Hello everyone,
I have the same problem with Qubino flush dimmers running app version (3.1.1). As discussed in this post, manual state change is not reported to homey. (Qubino Flush Dimmer manual state change doesnt be reported to homey). I think that’s why switching I2 or I3 doesn’t show any reaction in the flow.

I have set up my installation to use I2 and I3. With 16 switches that cost a lot of money for the electrician.

Maybe we should all write to support to make it clear that the problem is important.
