I have been trying to export a file to my device, but every time I try exporting it a display message says export is failed. I export using the option Highest quality available (have plenty of storage). Please help me on this issue.
Also the app is updated to the latest version available.
Could you please try sign-out & sign-in from the Lightroom mobile app and check if that helps.
Also, could you please share the screenshot of the error and let us know the mobile platform version you are on now?
