Old thread, but seems like the best place to ask...
I notice recently sometimes my LIKE button doesn't work. I click it - nothing happens.
At first I thought it was an iPad issue, but same happens on my desktop.
Then I thought maybe not allowed to click too many LIKES in a row -- but it's not that because sometimes it doesn't work when I haven't liked anything else in days.
Then I thought some posters can opt out -- but it's not that either, because I just tried to LIKE a post from someone who has other LIKES.
I noticed someone on the UA forum commenting on this: "I tried to LIKE your comment but it didn't work for some reason"
It seems completely random. Any other reports of this?
