One option: syncing: no connected device has the required version of this file - #8 by Cheer1
This is about some trash folder to added, but this is not the case here - only valid and required files are out-of-sync!
Another option: How to delete file with syncing: no connected device has the required version of this file
This is about changing the files (in that case nullifying them), scan again and then replace with the real content.
This is an idea I will try!
But of course it would be more easy to have a button or command to simply use the current local “versions” of those file.
And there are no other devices that could have changed content.
I will try and report back, many thanks!
