works perfectly, I checked 6.2.2 wordpress version. 8.1.9 php version.
Awesome plugin! It is compatible with ACF 6+ ?
Thanks!
Does exactly what it describes – simple and without hiccups, love it.
This plugin saves me a lot of time to manually code each relationship for each project that needs it. Works like a charm.
This is the second time I’ve needed to use this plugin in a year. Works perfectly. Thanks for creating and maintaining it!
