Unable to add background photo to device.

Having trouble adding a background after a accomplished day .I keep getting this message. I use to be able to. I've tried uninstalling App and reloading doesn't work. I know it works because I send picture to my sons phone then I log in to my Fitbit app on his phone I put background and then resend picture to my phone... Long process. Can someone help. Yes I gave Fitbit permission to access my pictures:
