Apologies if this is too frivolous of a question to warrant a topic but… I’ve noticed something and it made me wonder.
Lets say I click ‘Like’ on a post. Later, I change my mind about the post, or I clicked the wrong post to like, or I realized it was a sarcastic post, etc. etc. and I want to undo the ‘Like’. It seems that some posts I can’t unlike (it shows a icon when I hover over it with my mouse cursor), and other times I can unlike a post.
So why is this, or why does it happen?
