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

It's 12/15/21 and I am having this issue. It's very frustrating that only a few pictures upload out of 200. How can I fix this problem? 

mogellq, please follow the guidance at the top of the page to move to the build of Lightroom found on adobe.com rather than the one on the Microsoft Store.

This happened to me last month.. had to keep bugging them til they finally fixed it. 

I can't add more than 6 RAW files at a time. I hope it will be fixed soon.

Finally i have been plagues by the same issue. I have a seperate drive partiton for Lightroom data and today suddenly while importing it took awfully long, only to send me a message that some photos were not copied. It did manage to copy most of the files but after that it just doesnt copy any file anymore.

i tried copying the files from SD card to Hardisk and the importing, restarting, logging out but to no avail!!

i have been a registered user for around 3 years now am running the latest version (obviously) as part of my subscription. 

Waiting for a solution to this 

I am back to the issue of a stuck sync. Sync under the cloud on the top right shows a single pending item.

Click view pending or sync status; shows nothing.

The log format changed, and I cannot in the new format determine which image is stuck.

Same thing is happening to me, I can only edit photos in photoshop now for over a month. 

Thank you, Im about to try this now.

I was just going to post this here. Apparantly there is something wrong with the Microsoft store version of Lightroom that prevents importing.
