Ok… I made other tests…
As far I know this is not a cloud issue.
I created a new vault, and it was working, whether local (download folder/Test) or on my cloud, I could move the files, rename the files and seeing the changing name, move the folder etc…
BUT as soon i MOVE the files (excluding folder /obsidian where there is the config/workspace stuff), I couldn’t move any file, including the previously created folder.
So the pain in the *** will be to create new files and fill them with the content of the other notes… Hoping this error will not occur again.
Or do the move of files/folders or rename directly on Explorer.
When I update a note content, it updates automatically on the file explorer and on the cloud
