Many times when I create a new project I am seeing a "Request couldn't be processed" error show up in the Services window. Looking at Editor.log I can see this:

UPID request failed, Reason: The requested URL returned error: 422 (422).
Request Couldn't be Processed while processing request "https://core.cloud.unity3d.com/api/orgs/elvisalistar/projects", HTTP error code 422
.Refresh: detecting if any assets need to be imported or removed ... Refresh: elapses 0.002025 seconds (Nothing changed)

If you used the same name as another project in the org you’ll get a 422. As a tester I always create lots of projects called New Unity Project xx. These will exist in the org and this conflict will show up. We need to handle this situation more gracefully.
