Hello @orbitdesign,
Thank you for writing to us.
In order to set the duration of the membership or recurring payment for a group in ProfileGrid, you may use the ProfileGrid extension “WooCommerce Subscription Integration”, it automatically adds a user to the ProfileGrid group(s) when a WooCommerce subscription is purchased by the user and automatically remove the user from the ProfileGrid group(s) when the subscription expires.
For more details on this extension, please visit the links: https://profilegrid.co/woocommerce-membership-subscription/
I hope this helps, let us know if you have any other questions.
