I am running build 10549 and have made an album in the photo app. It says that the album is only local. How can I get it to sync to onedrive? Photo backup/upload is on and working.
It is currently not possible to sync albums across devices. There are quite a few entries for this in the Windows Feedback app that you can vote on.
A workaround would be to actually create the album on OneDrive rather than on the device (via the OneDrive app or a browser). This still wouldn't be a complete solution, but should be closer to what you want.
