Google Cloud Storage - files not showing
We have also seen this problem, and it seems that the issue is limited to buckets that have spaces in the name.
It's also not reproducible through the gcloud web console, but if you use gsutil to upload a file to a bucket with a space in the name then it won't be visible on the web UI.
I can see from your screenshot that your bucket also has spaces (%20 in the url).
If you need a workaround asap, you could rename your bucket...
But google should fix this soon, I hope.
