iCloud photo sharing limit reached -- new photo app I'm running the 10.3 beta on my iMac, using the new photos app.  I imported about 1,300 pics I took over the weekend (live performance) and want to share them online with some people.  

First thing I did was create three new albums, one for each of the performances, on my computer.  So far, so good. 

Then I used right click to share each album online via iCloud photo sharing.

Now, I'm getting notifications from Photos every 10 seconds or so with the above message. See image below.  It says activity will resume at 11:14 pm.  

What gives? I have space on my iCloud account, space I'm paying $10/month for, and I have plenty of available drive space there.  So why aren't the photos uploading, and is there a way to override this strange sharing limit?
There are multiple absolute and rate limits on iCloud photos. See this article for details:

Currently, if I had to guess, you hit one of the 24 hour limits and need do nothing but wait for the time to pass:

Maximum combined number of photos and videos from all contributors per shared album, per hour: 1000
Maximum combined number of photos and videos from all contributors per shared album, per day: 10,000


However, if you continue to have issues or are getting multiple notifications like your screen shot indicates, there could be a fault in the waiting loop code and you'll want to reach out to AppleCare to have engineering look at your account in particular. That isn't quick, but in the end usually works well if you are patient.
