While I understand that you need to keep the plug-n-play oriented customer in mind, I am disappointed with the way the integrations in general are handled.
I wouldn’t need a faulty door sensor and push notifications that require a bridge if there was zigbee support. Xiaomi throws out 100% reliable ZigBee door/window sensors for <10$ and notifications are much less important for me as triggering routines (which could even be notifications of course). Most of the inconveniences I have with nuki could be solved easily with my existing setup.
I assume that this is still a early adopter and tinker friendly community (plus the rbnb people). Giving us zigbee support early on would provide you with lots of feedback to implement the build in features in the best way possible. While I don’t think that the delays warrant an extended return period, I never got the bridge app to work and I would love to hear about some kind of compensation for the long delay of a feature that’s really critical for home automation.
While I still think that Nuki is a great product, by now I will jump ship for the first alternative that provides a integration solution instead of a IoT service.
Edit: give us a working raspberry based bridge solution and you have all the time in the world for ZigBee
