Keith - yes - the restore worked. most important thing. However, I could not run the restore a 2nd time without doing another snap.
So, if I recall correctly ... the steps I went through...
1. Create my Org & 2 vApps.
2. Create VMs
3. Attempt snap with policy down to the vApp level
4. Make changes to the vApp
5. SC restore via GUI.
6. Make changes again.
7. SC restore attempt via GUI.
failed.
8. Create another snap
9. Initiate a restore from the targeted snap.
I went through 2 iterations, with different types of changes. But, basically - the restore completes, and never updates the running state (no completion time) ... then it does not allow for a 2nd restore because it thinks it is busy.... unless another snap is taken in the interim.
