Welcome! This forum has a treasure trove of great info – Scouters helping Scouters! Just a heads up, though - all content, information, and opinions shared on this forum are those of the author, not the BSA.
I asked for the Up and Away to be added a couple of months ago and the reply I received from their IT team was that it was not a priority at this time. This was a VERY disappointing answer to receive given a lot of scouts have worked hard to get these active awards only to not be able to get proper recognition for them.
Britlin you can submit a paper advancement report to your council until Up and Away is supported in Scoutbook. Your Scouts do not have to wait to be awarded their patch / pin. We expect Up and Away and a couple other new Nova awards to be added soon, although we do not have an exact date.
I do not believe Nova patches/pins are restricted. You should be able to purchase them without an advancement report then update the records once the award is added to Scoutbook.
