Jira has started to change the file name and remove file extensions from attachments when they're downloaded (file name is changed to 'original (1)'). If the file extension is manually re-added to the document after download ie. .pdf, .png then the file behaves as it should, however it retains the 'original (1)' file name. We've not had this issue before, however it appears as though there was an update in the last few days which may be causing the issue?
Any advice would be greatly appreciated.
