I am currently using InstaWP for site development and can see that my one ACFPro activation there has used up my live licence.
This clearly isn’t a live site at all, and I intend to keep all my dev and testing sites on there and then upgrade to more ACF Pro licenses when the sites are ready to be deployed.
As the site’s URL ends in “.instawp.xyz” and is purely for development, can this be added without using a Pro licence?
There was a similar question asked here https://support.advancedcustomfields.com/forums/topic/devel-for-staging-development-sites/
This would be up to the developers. The developers do not visit or monitor this site on a regular bases and this forum is basically just other users answering questions when they can.
