Cloud files are not showing up

@Eva Laura5F9D , Can you please check if your Creative Cloud is updated to latest version. You can also do this by following below steps:

Open Creative Cloud.

click on cloud icon on top right corner.
Open preferences by clicking the gear icon.
Go into the General section of the window that opens, there you have two options to enable 'Launch Creative Cloud at login' and 'Always keep Creative Cloud up to date'.
Now logout from creative cloud and re-login with internet ON. If it start self updating or ask update creative cloud, let it happen successfully.
Check if issue is still reproducible.
If issue is still reproducible, Please launch Photoshop, click Help menu->SystemInfo and share the text in dialog. You can share it via zipping it into a folder & post it in dropbox or CC files.

After you've submitted the logs requested above, can you please try 

to restore your preferences using this manual method.

If it works, zip up the settings folder and post to dropbox or CC-files to share it so we can debug it.

If that doesn't solve it, you can quit Photoshop and put the Settings folder back.

@Eva Laura5F9D Could you please share logs? https://helpx.adobe.com/creative-cloud/kb/cc-log-collector.html 

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the Photoshop forum so that proper help can be offered.
