Why won't my polaroid SNAP print my pictures through the app?

I have used the snaptouch app for iPhone many times with my Polaroid SNAP to print pictures through Bluetooth from my phone.

Now all of a sudden it would print?

I have turned off - and on - both my phone and the camera

I have disconnected - and reconnected the Bluetooth and wifi

I have updated the app to the latest version

I have charged the camera

Any other ideas of what it could be?

It says its connecting to print... then it gets to about 95% and the loading screen disappears and nothing happens..
