You should update the plugin to pull the Order Number instead of the post ID (or at least make it an option). Those of us with custom order numbers would appreciate it.
Hi there,
Thanks for the suggestion! I can see why you would prefer the Order Number and I wanted to let you know that we're currently looking into offering what you are requesting. However, work for this has not yet been prioritized. We'll make sure to alert you via this thread should we have any updates or questions. Thanks again!
