Simply works – seems too easy

I had my host enable Let’s Encrypt, added the plugin, tested it by enabling HTTPS on a couple of pages (using the checkbox in the Page Editor). Seemed to be working, so, in Settings > General I changed my WordPress and Site URL to https. Still working :). After browsing the support threads someone pointed out you need to change URLs in your css (if you’re pointing to images). Caveat: the site I was working on is fairly simple, not sure if that made a difference. But I’m a happy camper.
