ICloud photos will not upload to creative cloud

I am new to Adobe.  I have the monthly subscriptions to use all of the apps inside creative cloud.  I am trying to upload some of my Icloud photos that automatically upload from my phone to my computer.  Not all do I want transferred to Adobe Creative Cloud, but when I choose which ones to import/upload, it just sits there saying it's copying or completing, but then it doesn't complete and skips to the next photo, and continues to do this.  Nothing ever actually transfers.  What am I doing wrong??  Please help and thanks in advance.
