Good Idea .... But

I have 4k pictures on my phone has stopped uploading pictures after 657. I have closed the app and restarted it and again stops at 657. So I powered the phone completely off and turn it back on. The app starts up and begins uploading and at 657 it stalls. I thought maybe 658 was video after 3 hours the app didnt go past 657
