P: (MS App Store Version) Message: Some photos were not added. Unable to copy file.

OH MY GOSH!!!!!!!!!  FIX THIS PROBLEM!!!!!!!!!!  Why is this takig months?  Thousands of people are telling you the exact same thing, and you're telling me that not one single human being at Adobe can figure it out after months?  Operating system- Windows 10, LR- whatever the heck version is on the Adobe website that people pay $10.99 a month for (shouldn't that part be on you guys to figure out)?  Open LR, click "add photos", choose photos from pictures folder, only a portion upload (if any), the rest randomly say "Unable to Copy File".  Pictures all taken at the exact same time, same settings, same camera.  No ryhme or reason for what ones will upload.  Hopefully Adobe will be refunding all customers for 2 months of hassle and a backlog of photos to be edited because the problem is clearly on their end.

FYI, reading the logs available from "Alt" key on the Account screen. I chased my issue down to a single file causing the problem. My laptop was trying to update meta-data on a file I deleted via the web interface.

This locked up the sync on the laptop. I ended up deleting the local library and re-adding the images which were still pending (not many).

Awaiting logs from affected customers

Please be sure to upvote if you are affected so we have an accurate count. 

I, too, can't get beyond the "Unable to copy" message. It worked for many photographs I took (stored on my laptop) and then it didn't. I'm not interested in fooling the program or an elaborate workaround. If I can't add photos, what's the point?

Same issue here! please fix this Adobe. Time is critical for creatives on a deadline and at the moment there i cant do anything because of this issue.

This is, what I hot from Adobe Support:

After rechecking, more entries have been added to the community. 

After reinstalling, the images could be imported into Lightroom without any issues. 

Please perform a complete uninstall from Creative Cloud and then reinstall. Use the Creative Cloud Cleaner tool to do this.

Hey! I just stumbled upon the same issue with my raw CR2-files, trying to import to desktop version of Lightroom on Windows 10. In my case, the workaround that seems to avoid the problem, was to launch the web-version (lightroom.adobe.com), sign in and upload there. 
Hope this works for others aswell!

I have reinstalled this program like 3 times now and it's still not working. Like seriously what is going on!!!!
