Question: I have shared my MyStreamingVideo channel on Facebook but the details (title, description and thumbnail) are not the correct ones. Why is this happening?
Answer: The Facebook has a caching system build and if you have recently changed the details of your channel (title, description or thumbnail) then it may take some time until the changes are updated on Facebook cache.
If you have a developer account you can try to force Facebook to automatically extract all the info on your meta tags and also clear the cache of your page by entering it on the URL: https://developers.facebook.com/tools/debug
