Easily seen in the JSON result from this:
https://www.linkedin.com/countserv/count/share?url=https://www.linkedin.com
Which currently returns:
IN.Tags.Share.handleCount(
{
"count":0,
"fCnt":"0",
"fCntPlusOne":"1",
"url":"https:\/\/www.linkedin.com"
});
Apparently it affects most of the LinkedIn Share buttons/counters out there on the web, including WordPress and other blogs. This has been "broken" since late last week (13 Jan 2018).
I opened a ticket with LinkedIn support. Response was to post here, as this is where the LinkedIn Developers support resides. Hoping for a response that says "Oops, we'll fix this." Or, if deliberately crippled, an announcement that says so. (Twitter made a similar move a few years ago. It was unpopular among developers, but we've moved on.)
