Got it — thank you for that awesome insight, John!
So to be clear about one thing — even if I know the meta_key of a field created by The Events Calendar — _EventCost, for example — I would need to create an ACF field ALSO called _EventCost in order to write to it?
That being the case, I could not include the plugin’s _EventCost field somehow within my acf_form call?
I think I have the right — does that sound correct?
