P.S. I clicked on the View on the Web Link and again on the Adobe web site there is the collection name, but 0 pictures. This is after 30 minutes.
The problems I reported on happened with my Windows Desktop computer. I made a collection on my McBook Pro, signed in there and was able to sync the collection, view the pictures on Lightroom Adobe.com and on my iPad.
I went back to my desk top, signed in and tried to sync and nothing happened. Zilch. I read another thread in this forum, where it was suggested that you Delete All Data in the Lightroom Mobile preferences. When I did that, the message in my desktop Lightroom said Syncing 26 pictures and counted down to zero. However both lightroom.adobe.com and my iPad showed No Collections and no pictures. I went back and signed my MacBook in again and the transfer works as expected. Is there a problem unique to the Windows version of Lightroom? I'm at my wits end. Please help
Do you have a firewall setup in Lightroom on the Windows machine? Perhaps it is blocking the outgoing traffic from Lightroom.
I went back to the Windows machine and tried a different catalog and it worked fine. So I went to the original catalog and it worked. I don't know what the story is, but for now it seems to work.
