Hi there, I'm trying to backup my settings from my Nexus 7 to my S6. I save the backup file to Dropbox. When I try and restore, I'm told the zip file isn't a valid backup. Any ideas?
As noted in the changelog in v9.3, backups made prior to v9.3 will no longer work, due to the massive new change in data architecture for multiple servers.

You're still in luck though.
