My published links are now back up and functional and I can browse the list of all my cloud XD files, but when I try to open cloud files in XD I get the error message "Sorry, we can't open this document." This is happening to any cloud document I try to access. I didn't start seeing this message in my documents until after the cloud services came back online around 3:45pm EDT or so. Please help, I have no way of accessing any of my historical files.
Step 2.Follow the instructions mentioned on this page step by step (https://helpx.adobe.com/xd/kb/issue-saving-xd-file-creative-cloud.html). Before proceeding to the next step. Please upload the logs to CC or Dropbox and share the link with me via PM (click on my name and hit the message button on my profile). This would help us to get to the root cause and investigate further.
I installed Creative Cloud and XD on another machine and was able to sync libraries and open all my files without issue. So I went back to my original machine and uninstalled, reinstalled, and resynced all my creative cloud files and I'm back in business.
