Any ideas?

My phone did a regular update today and I thought I'd also update the apps I use.
After deleting the Blipfoto app, I downloaded a new copy, installed it, signed in, and saw that no images are showing up. 
None. Nada.
Just the images are missing.
And it's the same on every screen, my page for the day, the grid view of those I follow, and so on.

I've tried uninstalling and re-installing, rebooting, the works, all to no avail.

Any ideas?

Ah well...
