“I can confirm this issue exists. It’s ok if i use native sync app, but if i try to use a 3rd party WebDAV app i have the following: 1) open the ms exel file and do some changes. (let’s call the file - List.xlsx),there also created ~List.xlsx in a file directory 2) Click save, it says can’t save file. 3) I click close without saving. 4) ~List.xlsx becomes 1KB long and my original file List.xlsx disappears. File with some random characters, like DS832DH.TMP appears instead of it, it has the native List.xlsx consist and length”
