I've been uploading images today from LR6 to FB. 200 images were uploaded successfully, but now I'm unable to publish anything else. LR tells me its unable to retrieve album information. It also informs me to check the app in FB. I've checked the app; I've tried removing the app and reauthorizing. I've tried unauthorizing and reauthorizing; I've also tried disabling and reenabling. Nothing works. How can it work one minute and not the next?
