It seems that when it rains, it pours. As has been reported in the forums, the Splash Screen Control plugin has stopped working for some Corona developers. Fortunately, as of this post, we believe we’ve solved it.
The problem originated around two different issues. For Corona Native users, a change to a background API was being applied incorrectly. This was resolved last Friday and we had Native builds back up-and-running quickly.
For Corona Simulator users, we addressed an issue with the cache busting after your plugin expired and you renewed, but that caused a database issue involving multiple records. We have been working diligently to solve this matter and you should now be able to resume builds using the Splash Screen Control plugin.
