I just found out the issue

1. Only first login redirect feature does not work
2. Buddypress profile completion plugin redirect takes priority over all login redirects while using plugin like
1. https://wordpress.org/plugins/peters-login-redirect/
2. https://wordpress.org/plugins/bp-redirect-to-profile/
3. https://wbcomdesigns.com/downloads/buddypress-redirect/

I just found out the issue

1. only first login redirect feature does not work
2. Buddypress profile completion redirect takes priority over all login redirects. I have tested this with various plugins like
a. https://wordpress.org/plugins/buddypress-profile-completion/
b. https://wordpress.org/plugins/peters-login-redirect/
c. https://wbcomdesigns.com/downloads/buddypress-redirect/

First of all I have this code below

 // filter buddypress profile completion redirect url to a custom page.
add_filter( 'buddypress_profile_completion_redirect', function ( $redirect_url ) {
	return get_permalink( 34168 );
} ); 

34168 = complete-profile page

 function buddydev_skip_redirect_on_non_bp_pages( $skip ) {
    if ( ! is_buddypress() ) {
        $skip = true;
    }
    return $skip;
}
add_filter( 'bp_force_profile_completion_skip_check', 'buddydev_skip_redirect_on_non_bp_pages' );  

 function buddydev_redirect_to_news_feed() {
	
	if ( is_user_logged_in() && is_front_page() ) {
		bp_core_redirect( bp_get_activity_directory_permalink() );
		exit( 0 );
	}
}
add_action( 'template_redirect', 'buddydev_redirect_to_news_feed' ); 

Now when a new user register

1. All first login redirects should go to (welcome) page instead of (complete-profile) page. Currently, by default all first logins redirect to (complete-profile) page by BuddyPress Profile Completion plugin.

2. I want member types pro first login redirect to take priority to (welcome) page over the BuddyPress Profile Completion plugin

Honestly, I was thinking why you never created an all comprehensive buddypress redirection plugin. The plugin would handle the following settings

1. First login redirect for new users
2. Second login redirect for new users
3. Normal login and logout redirect for all users
4. Option to select redirect page for logged in users while trying to access the home page (see third code I sent)
5. Login and Logout redirect options based on member types.
6. Login and Logout redirect options based on roles.

Now all your other plugin can work or integrate effectively with this redirect plugin.
PLUGINS LIKE
1. Branded login plugin
2. Member types pro plugin
3. Profile completion plugin

What do you think?
