I have uploaded a file using the Nextcloud Android app to my Instant Upload folder. But when i want to delete the file using the Nextcloud web-interface i get an unable to delete message
This is the corresponding log entry in the log

I created a new picture and nextcloud uploaded it to InstandUpload and now i`m able to delete the file without issues. So it is not always an issue
