Photos Sync between iOS & Mac Issue (iCloud)

I am testing out the Beta and want to see who else has been having this problem.

I have about 35,000 pics, and both of my Macs are perfectly in sync.

On iOS however, both iPad and iPhone, the librarys will sync and then get stuck in a preparing to upload, upload, and download loop.

And then nothing happens at all and the library is just static and stuck on items to upload.

Anyone else experiencing this?
