I'm having conflicting reports for our users that people that share Object Graph objects to their wall, are sometimes showing the Object title and other times not. Specifically, every test I do on my own account shows the Object Title, but on their Mobile apps - it doesn't appear. I've tested the Open Graph debugger.So I have a couple of questions:
- Is there a length limit on the number of characters?
- Does Facebook not show the whole Object.title on Mobile?
- Does Facebook scrap the OG tags and if it can't find them or if it timeout do they not receive them?
Here is my sample OG url:

What can I do here? What am I missing?
Please refer this link. Its working fine for me. And I think this is the only solution.
I have a workaround:
- To your "beer object" add a property "name" of type string.
- Edit your story "drank beer": In the One to One without object title change the story to " drank a {beer.name} via Untappd" from " drank a {beer.title} via Untappd"
- Save the changes.
- When creating the beer object, then along with "title" provide same string to the property name.
- Publish the story.

Also you can try set Facebook share link like:
