Intermittent issues with Pay with a like

So I've been having intermittent issues with PWAL in that sometimes it shows the content and sometimes it won't. People share my content but it doesn't make it visible after doing so. I've had the same issue myself, but on some posts it works just fine. Has this happened before? I really wanted to use this plugin, but if it doesn't work properly then I won't use it. Thanks
