Several times I receive request to shorten / lengthen future reservation. While OR sends and auto-email to the guests stating how dates changed. While OR does suggest to recalculate charges, I do not see anything that sends updated charges table to the guest. is that something missing in my set up? I had to send updated charged (for example, for one more night or one less night) manually.
There isn't currently an auto email that goes out because of all of the different reasons that might cause the charges to be changed.
Instead, the best thing to do is to make an email template for the current billing summary and then go to the booking and do an "Email this guest". Here's an example template: https://www.ownerreservations.com/support/articles/template-receipt-billing-summary
