LinkedIn share count API (/countserv/count/share) always returns "0"

Question

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.)

Further to Chris Hemedingers response, this feature has now been entirely deprecated

Deprecating the inShare Counter

As you can see they have deprecated this saying:

The share count on its own doesn’t fully reflect the impact that a piece of content delivers, and we encourage publishers and other content creators to leverage the inShare plugin as a way to drive conversation and engage with members on LinkedIn.

They then link to the Documentation saying:

Share on LinkedIn plugin will no longer return share count.

This is massively inconvenient for my company as we have just finished construction of a suite of tools powered by this.
