Multi-device sync issues
When synchronizing files with webDAV, only pdf is downloaded. You can't open a file with zotero on another device
Component returned failure code: 0x80520015 (NS_ERROR_FILE_ACCESS_DENIED) [nsIFile.remove]

If yes, it is probably this problem: https://forums.zotero.org/discussion/comment/442537#Comment_442537
[As already mentioned in your previous post.]
The devs are investigating. The latest status on this is: If you really want to get rid of this sync error, you could try to install the latest Zotero 6 stable (download the .exe file at Zotero 6.0.27 and run it on top of the existing installation, no need to uninstall Zotero 7 beta before), and then reinstall Zotero 7 beta. This worked for me to get rid of the sync error, but it will come back again if you sync more files across devices.
