After 1 year of a persisting issue that made LL unable to sync and copy accounts to the beta grid has now been resolved, and you can request to get access to Aditi!!
How to gain access?
1) Log in to your SL account and visit https://lindenlab.freshdesk.com/support/home
2) On the Submit A Ticket page, select Account Issue as the Issue Type
3) For the Account Issue dropdown, select Viewer Login Issues
4) Enter the name of the avatar you'd like to use on the Beta Grid and in the Please describe the issue box, explain that you'd like access to Aditi or the Beta Grid.
5) Click Submit to send your request to Support.
Usually someone from LL will respond to you very fast (mine took 1 hour)

Have fun testing on the beta grid
