Why won't LinkedIn update when I replace my Slideshare presentation?

I have the same problem. Got it to work briefly, then not work, then almost work again.

SlideShare offers very little explanation about how to set up the Linkedin connection in their preferences. It's a classic case of poor IT communication skills. That is the problem.

Here's what I've sort of figured out... so far. This may or may not help:

If you make your slideshow viewable to "everyone", make it embeddable, and do not choose an invisible url, it may show up on LInkedin.

But... you may have to re-establish the link between SlideShare and LInkedin after making any changes to your Slideshare prefs. Plus, any changes you make to SlideShare may not always happen after clicking 'okay'. You may have to do the same change more than once before it stops reporting an error 504 or whatever. And there seems to be a very long delay before your preference changes take effect on your LInkedIn profile. It is not instantaneous.

Despite Slideshare's cryptic interface... I actually got my slideshow to work for awhile on LInkedin.

But... then I noticed that within one day my file had been viewed by 54 people and downloaded by an anonymous name overseas. And it was not from my LInkedin account.

I became concerned that my private data was being harvested by some scam artist... so to protect my info, I changed my prefs again... to only allow access from 'my connections'. But doing that erased it from my LInkedin Profile. Not what I wanted.

Conclusion:
I believe SlideShare is about making your file 100% available online for anyone to use with no protection or privacy whatsoever. If you put any privacy limits on it in your Slideshare prefs, and it will no longer show up on your LInkedin profile.

In other words, for your slideshow to be seen on Linkedin, you need to make your Slideshare prefs totally without limitations... so anything you upload becomes the property of anyone who views it. You are giving away your file and all the info it contains to anyone in the world who wants it.

If I am wrong, then I challenge Slidehare to explain how to set up a link with LInkedin that is private.

Slideshare apparently offers no helpful feedback or any real support that would allow us to use it as a way to safely show images on Linkedin.

Get it to work and your images may be used by a Russian hacker to spam a Chinese diplomat in New York who is working with a pirate with an online book business.

Slideshare over-promises and under-delivers. If we get any feedback from them on this issue it will be a miracle.
