Hi @will-lawrencefuturform-co-uk
ACF has a feature that allows you to create a custom location rule, but it depends on how Restrict Content Pro adds the Members page. You can only show the rule for an edit screen (page / post / user / taxonomy / attachment / etc). This page should give you more idea about it: https://www.advancedcustomfields.com/resources/custom-location-rules/.
If the Members page is not an edit screen, then the only thing you can do is to use the acf_form() with the “form” option set to false. Please bear in mind that you can use acf_form() on the backend too, but you need the correct way to process the data.
I hope this make sense 🙂
