I bought more iCloud storage but my Photos doesn't recognize
I purchased iCloud storage on my MacBook and when I go into my iCloud drive, I can see that extra storage is reflected there. But my Photos doesn't know this and keeps telling me that my iCloud storage is full and is permanently stuck at where it last stopped its upload. So it tells me how many photos are still left to be uploaded but they don't get uploaded automatically. I don't know how to start this manually and get Photos to see that I do indeed have extra storage. Any help would be appreciated.
MacBook Pro, OS X Yosemite (10.10.5), Photos
