Hi Anisur,

Thank you for the question.

We are not using PMPro for any of our project, so I will post a sample code which you can give to their support and request them for the code to update the membership.

// update something about user on profile completion.
add_action( 'bpprocn_user_profile_completed', function ( $user_id ) {
	// add code to set/update the membership for the user.

} );

Please give them this sample code and request them to provide the code for updating the membership for user.

Regards
Brajesh

You are welcome.
