Unfortunately, Flickr have recently (~ 14 September 2016) made a change which has resulted in all Flash-based applications (not just SimpleViewer) being unable to receive data via their API.
Please see this forum post for more information: https://www.simpleviewer.net/forum/view … 014#p53014
We have posted in the Flickr Help Forum ourselves but have not yet have an official reply from Flickr staff.

The change that Flickr has made affects only Flash galleries so the Mobile Player within SimpleViewer (the HTML version of the gallery) is still able to display Flickr images (which is why you still see your images on your iPad).
Perhaps the best course of action at the moment would be to use the Mobile Player for all browsers and devices as noted in this forum post: https://www.simpleviewer.net/forum/view … 008#p53008
It might also help our case if you were to post a reply in our Flickr thread: https://www.flickr.com/help/forum/en-us … 994865581/
Flickr might be more inclined to revert the change if they are made aware of how many users have been adversely affected.
I am sorry for the inconvenience that is causing but, as it is beyond our control, I also thank you for your understanding.
If and when we hear any more news about this issue, we will be sure to post in the SimpleViewer forum thread regarding this issue (first link above).
