Hi @Hube2
Good questions.
There can only ever be 1 ACF instance, so it’s the first ACF files to be included are the ones which are used.
A plugin will load it’s files before a theme, so it is possible that a users plugin will run a version of ACF PRO which is not desirable for your theme which uses ACF PRO. I ma not sure what the solution for this is…
If the user adds a license key and attempts to update, it will most likely fail due to WP not understanding customer plugin paths, but this is untested as of today.
The JSON load paths have been setup as an array to allow for everyone to add their own without removing any other.
Hope that helps answer the questions.
Thanks
