There is a service issue impacting the ability to generate thumbnails. We are actively working on this and will post here when fixed.Anonymous supported this idea ·Anonymous commented
Having the same issue, as of today. Uploaded a bunch of photos last night. Thumbnails still display for all of them. Went I went to add another file to the folder, I'm getting the same result as others. When I click on the placeholder (mountain) icon, instead of displaying the photo, it starts a download process. It sure seems like Microsoft updated the application and broke it.
