Problems with AirBnb Integration

In the city I live in, we have a limit of max of 60 nights per year. As I am already coming close to this number, I have paused my listing on Airbnb to prevent overbooking and needing to cancel bookings.
But now the reservations I already have no longer get an email from Nuki with the code and the instructions to install the app. To me, this looks like a bug. Is this a known issue?

Please contact our support via the Nuki App (Menu > Help > Contact Customer Support) as this is an individual problem and might require sharing logs and other sensitive data.
