Hi Amir,
Please try this code

/**
 * Remove associated groups when member type is removed.
 * It will not fire if member type is changed.
 */
add_action( 'bp_remove_member_type', function ( $user_id, $member_type ) {

	if ( ! function_exists( 'bpmtp_get_active_member_type_entries' ) || ! function_exists( 'ld_update_group_access' ) ) {
		return;
	}

	$active_types = bpmtp_get_active_member_type_entries();

	if ( empty( $member_type ) || empty( $active_types ) || empty( $active_types[ $member_type ] ) ) {
		return;
	}

	$mt_object = $active_types[ $member_type ];

	$group_ids = get_post_meta( $mt_object->post_id, '_bp_member_type_ld_groups', true );

	if ( empty( $group_ids ) ) {
		return;
	}

	foreach ( $group_ids as $group_id ) {
		ld_update_group_access( $user_id, $group_id, true );
	}

}, 10, 2 );

Please do note that this code may not work in BuddyPress member Types Pro 1.5.0 coming out this week(when we move away from post type).

Hi Amir,
Thank you for the reply.

1. Member Types Pro 1.5.0 is for BuddyPress 7.0 or above. In BuddyPress 7.0, there is native UI for creating members types, we are moving our additional functionalities to it.

2. Yes, within a week.

3. The problem is we have use get_post_meta in some of the custom codes. These custom codes like above will stop working. Other than that, the plugin and its functionalities will work without any issue.
