Uploading issues

[Rose640]

Recently i unchecked the 'Auto upload to OneDrive' for my photos and videos. Now i want to enable it again, so i did. Now, the problem is that the old photos won't start uploading automatically, and i really don't have time to manually check and upload 100+ photos and videos (i've tried, but the ******** photos app randomly unchecks selected photos, so it's practically mission impossible).
Help needed.

manually would be easier if you connect to your pc

Not an option, since my PC's dead for some time now.
