I am unable to download multiple photos from my Google Photos account when I could before.

Google photos is my primary cloud storage and all my photos are backed up there, my own screenshots everything. Now since I have had a Samsung I have been able to re-download the photos back to my phone is necessary, if I am selling something i need the picture back but now I am unable to do so. I can only restore a picture but one at a time. Multiple photos cannot be downloaded?

I have gone into the Application Manager under Photos (Google) and cleared the cache and forced stop and this has not fixed the problem.

Any help would be greatly appreciated.
