Hi Arlex
That doesn't really help as users are not going to investigate where the Flickr 'share' link leads. They are just going to keep telling me it doesn't work.
This isn't an issue on any other social network.
The user should still be able to add the link as text even if the system fails to fetch a preview, but there isn't even an explanatory warning message give the system just doesn't react.
This is a bug that needs fixing not something users can be 'educated' to workaround.
