On my website, I have a plugin called "Contact Us" that was created and is being operated by Dropifi. Lately, I've been working on optimizing my site for SEO/Speed using Google's PageSpeed Insights tool. I enabled compression with GZip for all elements on my site, but Google is indicating that .js and .css files hosted on Dropifi's servers need to be compressed too. It's also suggesting that browser caching should be leveraged for these files as well. Is there any way to address this issue without having to remove the plugin?
