@stevethesquid - The Spark Dev IDE still uses the cloud functions to do compilation and flashing of the Spark Core. If you were having problems with the programming over the air before, it’s likely that you will still experience these problems. What you may need to do is compile and flash everything locally. There are instructions in the Spark firmware repository for getting it set up. It looks like @suda is or was working on a local DFU flash version of the IDE at some point.
@pellson60 - This is a known bug. You can track the progress of the bug report in this issue in the GitHub repository.
