From my iPad Pro, I can't see a cloud document file that should be there. I can see the file on cloud from desktop version of Photoshop.
When I firstly tried to open the file on my iPad, the file was there. The file was large; it took some time to download. The download dialog was shown. And then, my iPad went to sleep automatically. I woke my iPad, I no longer can see the file. The download dialog was gone. Download didn't seem to be continuing. The file was not shown in the Cloud Documents. I still could see the file on cloud, from my desktop PC.
This happened to me twice. First time it happened, the file re-appeared after more than 24 hours. The second time, it is now, I'm waiting for the file to appear again.
I updated to Photoshop on the iPad 1.0.1. The problem is still there. Today, I uploaded another file from my desktop PC, started downloading on my iPad, it went to sleep, the file disappeared. It's completely reproducible.
