Everything was working perfect and I have shared some articles via the link. However it has now stopped working. I can click on the linkedin button in the article and this will trigger the linkedin appi, showing the share menu, but when I press share to actually share the article on linkedin, it just blinks and nothing is happening.
Not sure what would have changed. We'll gladly help investigate though. Can you let us know a URL where we can see the issue?
On your end, I'd recommend trying from a different browser and checking if you have any anti-virus or security programs enabled. Those can try to prevent social network sharing, depending on their configuration, and they may just be doing their job to prevent the social network aspects of some sites from working properly.
