Linkedin contacts sync

It was some time ago when Facebook has given up on BlackBerry. No API ment among many others no contact sync. I resolved it in such a way I have installed an old version of fb App (which does nothing besides syncing contacts) and I use web version.

Now it is Linkedin that stopped syncing. Is it temporary problem I am experiencing or is lack of syncing contacts with Linkedin a permanent state?

If so, is there a way to resolve this the way I did with FB?

I tried installing an older version but there was a pop-up stating "the newer version is installed on your device, uninstall newer version before installing the app". No newer version installed whatsoever.
