Hello Toastyblocks,
We are working towards the v2 Skeletal being backwards compatible, but as with any developer beta version you may experience some issues as this is not a final consumer release. We would recommend returning to v1.2 for a consistent experience with your Airspace apps right now.
We’re also working with Airspace developers to ensure their experiences remain consistent and have ample time to take advantage of our new API features before the final consumer release.
