Hi I am using one drive app over a year since I bought my Lumia 520. But suddenly since a week the one drive app showing zero photos, empty folders. But I can see all the photos when I log in via browser. But not in the wp 8.1 built in app.
I have a similar problem. A folder shared from another account, shows up as shared folders in my phone app (Lumia 520, WP8) but when I try to open the shared folder it says "this folder is empty". Doing this on a laptop/computer has no problems.
