Hi @Gillian186, @Branka-and-Silvia0,
Well, I don't think it can be called an experiment anymore (it has already been around, since early 2018).
We hosts are not aware of these situations, as our dashboard will show us an accepted state of the booking.
And all sort of issues can happen. Even a simple change of credit card, between the first write off and the second write off, can cause issues.
It looks like, there may be a little trick though. To recognize such situations. But I have to do some further analysis. To ensure my assumption is correct.
