Uploading Documents problem

Not working.

Stopped working sometime yesterday.
For a while, seemed to be taking longer, but came up within at most 2-3 minutes.
Then switched to spinning, never coming up, which is still the case.

On a profile, choosing Add Document, choosing from one I had previously downloaded.
Have tried several different profiles, different documents.

Could this be a problem with my device, not general?
If so, any ideas?
I was thinking once upload document is clicked, the processing is all by Geni, not on the Tablet (the device I use at home).
But it works fine on a PC at a University Library. Still just spins on my Tablet.

Maybe fixed - one just uploaded - and quickly.
Crossing fingers it continues.
