If you’re using View Seeker and aren’t getting any results when searching using the Flickr service, the problem appears to be with Flickr’s search. The search is executing in the app correctly and not returning an error, however no results are returned, and hence the reason the app is showing a blank page rather than an error.
You can find a bit more info at this link.
Unfortunately we just have to wait for Flickr to fix the problem. Will keep you posted.
