We've seen such explosive growth over the last few weeks that it’s causing a little lad on our servers. Please restart your phone and check back to your photo in a few minutes and see if it works. Most of the time, if a photo doesn't play right away, if you come back in 10-15 minutes it will work fine. Please try again :) The photo should be recognized and start to play within 3-5 seconds.
Cellular connectivity and WiFi connection can be a factor as well. If a photo takes a long time to play, it could have something to do with your cell connection too. So check that also.
Lighting could also play a role. Hyperphotos have a hard time being recognized in dark rooms, you can hit the “Flash” button in the top right corner of the Hyperphoto viewer to turn on your flash and get a little more light. You might have to angle your photo a little bit to get the glare off, but sometimes that fixes the problem too.
