Do I need to leave my Koofr iOS app open while I am uploading files?
Yes, the app must be opened in the foreground. You can leave the app open, and it will keep the screen awake until all files have finished uploading.
Note: For automatic background uploads, you need to use iOS 26.4 or later, Low Power Mode must be turned off. Read more about it in question I am using the latest Koofr iOS app and iOS, but my background auto-upload is not working. What should I do?.
