Hi Nick,
Sorry for the late reply.
I will start with the question #2 (“shipping method”):
Please update the plugin to the latest version 2.1.0. You can now set the required shipping method(s) with our “Rule #X > Conditions > Shipping methods” options.
As for the question #1 (“booking”):
I’m not sure if I got it correctly. Do you mean you want to change the status of the booking itself? Or of the related order? Also, as I understand, the booking plugin is paid, correct? If that’s the case, could you please send me its zip for testing (my email is [email protected]).
