I think you also need to close down the browser, but Yeah I usually works on the days when the like feature is buggy. Doesn't work all the tine though.

On main boards it seems to work...but not in groups. Frustrating and irritating.

The "Like" button does not work for me for days at a time. It's frustrating.

Signing out did not fix it.

It works for me in places but doesn't work in some of the groups I belong to. I tried signing out and back in but it didn't help. I just tried it on your post and it does work. The administrators still have some work to do.
