Azure Webapp NGINX conf not removing .php extension

Question

I have an issue with my nginx server on Azure app service where I'm trying to remove the .php extension from my URLs but I can't seem to work out why my config isn't working.

I've followed the instructions exactly from here https://azureossd.github.io/2021/09/02/php-8-rewrite-rule with one exception of replacing index.php with $uri.php. I know the startup script (/home/site/startup.sh) works as it breaks my site when I restart the service.

My conf file is:

server {
    #proxy_cache cache;
    #proxy_cache_valid 200 1s;
    listen 8080;
    listen [::]:8080;
    root /home/site/wwwroot;
    index  index.php index.html index.htm;
    server_name  example.com www.example.com; 

    location / {
        index  index.php index.html index.htm hostingstart.html;
        try_files $uri $uri/ /$uri.php?$args;
    }

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /html/;
    }
    
    # Disable .git directory
    location ~ /\.git {
        deny all;
        access_log off;
        log_not_found off;
    }

    # Add locations of phpmyadmin here.
    location ~ [^/]\.php(/|$) {
        fastcgi_split_path_info ^(.+?\.php)(|/.*)$;
        fastcgi_pass 127.0.0.1:9000;
        include fastcgi_params;
        fastcgi_param HTTP_PROXY "";
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
        fastcgi_param QUERY_STRING $query_string;
        fastcgi_intercept_errors on;
        fastcgi_connect_timeout         300; 
        fastcgi_send_timeout           3600; 
        fastcgi_read_timeout           3600;
        fastcgi_buffer_size 128k;
        fastcgi_buffers 4 256k;
        fastcgi_busy_buffers_size 256k;
        fastcgi_temp_file_write_size 256k;
    }
}

As per Nginx: Remove .php file extension from URL, use rewrite-uri in /etc/nginx/conf.d/domain.tld.conf

location / {
    try_files $uri $uri.html $uri/ @extensionless-php;
    index index.html index.htm index.php;
}

location ~ \.php$ {
    try_files $uri =404;
}

location @extensionless-php {
    rewrite ^(.*)$ $1.php last;
}
