A have a number of clients whose thumbshots occasionally disappear for significant periods of time. I re-submit them and get a message "The URL cannot be updated or update is already in progress."
Why would it not be updateable or why does it take so long to update once it existed? I display my clients home pages on my site but their site does not actually use thumbnails. Any clarification would be appreciated.
