I'm trying to use LinkedIn member profile plugin, but didn't get lucky in making it working reliably.
The issue is that without any visible reason (as far as I can tell) sometimes it's working and displaying profile card (with or without me being logged in into linked in), but sometimes it makes requests behind the scene but displays nothing.
I've noticed though, if I don't have open LinkedIn session, most likely it will fail to display. In case I logged in before, it shows my profile most of the times, but sometimes fails as well. In documentation they didn't say anything about requirement of having an open session, so I assume it should work the same way for all the cases.
To test it I created a simple html file, in a body of which I put a code generated on Linkedin website. See a plunker below as an example of code. I run it on local webserver under http or https, trying different domains, the same thing.
I noticed when result is unsuccessful one of the responses looks like that:
