Wd photos upload stops unless screen is active

Trying to upload photos from my phone (galaxy 5) to mycloud mirror over wifi. Upload stops whenever screen is off. Phone is not sleeping, and even if it was, phone is set to keep wifi on. But when screen turns of, the backup stops. Using latest version of wd photos.


Verify the energy savings option on your Smartphone.  It is possible the phone is going into energy saving mode and turning the app unusable when the screen goes off.
