Just tried to like your post--successful. Am on full site, desktop, Windows using Chrome browser. Interesting, yesterday and most of the past few weeks, it didn't work. And that was on Chrome, Firefox, and Brave. But on my phone (Android 9.0), like button has always worked (Chrome and Brave).

Maybe it's just a weird intermittent gremlin. It's not a dealbreaker for using the site, just wondered if I'd been black-balled and my "liking" privileges revoked, heh-heh.
