Nuki 4 pro Matter doesn't work

[Juergen (Jürgen Pansy)]

This is a know issue. See:

Smart Lock (4th Generation) - Set up Home Assistant for Remote Access via Thread

It’s a problem with how the Nuki Android App communicates with the Smart Lock and is most likely also mobile phone dependend, because not everyone is affected. It has nothing todo with your TBR at that point in the process. We’re looking into it and will try to resolve it with the next update.

Only workaround for the time beeing is to use an iPhone or try another Android phone. Will be fixed in the next Android App beta.
