As of this morning I am able to create and edit apps. The app that I created is using the same name that I attempted to create yesterday so I know that the issue is not duplicate names.
Ha! Hello. Yes, I'm here. The Sencha.io team is quite large. Chris and Jason answer most of the forum questions now.
We're all working away on the next release, which includes fixes for all known issues.
@dpwilson Yesterday one of the servers failed which caused app/group creation to fail. It was going very slowly, rather than not working at all, so we didn't notice until the evening. I fixed it last night.
The next release is built on all new infrastructure, which is much more resilient to failures like these.
